Dermot Morgan died only one day after filming the final episode.

After the broadcast of the first episode, the network received just two complaints: one criticizing it for being too anti-Catholic Church, and the other criticizing it for being too pro-Catholic Church.

Introduced the word "feck" to the English language. It was already common in Irish English. Vernacular usage of feck in the expletive sense is syntactically interchangeable with fuck, though it has no sexual connotations.

Dermot Morgan announced that he was leaving the series and that Series 3 was to be his last, because he wanted to move on and do other roles.

The band Radiohead are very selective about which movies and TV shows they allow to use their music, but were reportedly very happy to allow one of their songs to be used in the series, to plunge a character, who had just recovered from a bout of severe depression, back into the depths of despair. The song was Exit Music (For a Film), while the character in question was Father Kevin in the last episode, Going to America (1998).

In the DVD commentary, Graham Linehan said that he considered Bishop Brennan to be the arch-enemy of Father Jack Hackett, because Jack had the potential to become a bishop, but failed where Brennan had succeeded.

In Father Ted: The Mainland (1998), when Ted talks to the police on the phone about Mrs. Doyle. Mrs. Doyle's first name is bleeped out. Mrs. Doyle's first name was never revealed. But in the script, her name was revealed to be Joan.

The character of Mrs Doyle is based on the mother of writer Graham Linehan.

Frank Kelly passed away on February 28th 2016 at the age of 77 when he suffered a heart attack. Dermot Morgan also passed away on February 28th 1998 also died of a heart attack. Kelly died 18 years to the day Morgan died.

Neil Hannon of Irish pop band, The Divine Comedy, wrote the music for "My Lovely Horse" for the episode "A Song For Europe" as well as the main theme tune. Father Neil Hannon was one of Mrs Doyle's numerous hilarious guesses of the name of a visiting priest, who turned out to be Father Todd Unctuous.

The theme tune to Father Ted was written by Neil Hannon of The Divine Comedy. It was later given lyrics and became Songs of Love on their album Casanova.

During the shopping centre scene, the young blonde child shouting "Feck" is actually Director Declan Lowney's son.

It is a common misconception that the show was originally pitched to Radio Telefís Éireann (RTE - the Irish National Broadcaster), and executives passed chiefly because it seemed too similar to an unsuccessful show produced by RTE called Leave It to Mrs. O'Brien (1985) starring Irish stage legend Anna Manahan as an overprotective housekeeper to two Dublin priests. This myth has been used to deride RTE on many occasions, but the show's authors have repeatedly stated that the work was never at any stage offered to Ireland's national broadcaster (despite the show's setting and cast) and was always intended to be pitched to Britain's Channel 4. Ironically, as of December 2020, the series continues to be on Ireland's RTE, in near continuous re-runs, since the mid 1990s.

Originally Mrs Doyle was going to be a love interest for Father Ted but this was ultimately scrapped, however most of the dialogue is still the same.

Graham Linehan revealed in a Channel 4 documentary Father Ted: Unintelligent Design (2011), that Dougal was inspired as a cross between wide-eyed bartender Woody from Cheers (1982) and the roadsweeper Trigger from Only Fools and Horses (1981). For his portrayal of Dougal, Ardal O'Hanlon drew inspiration from Laurel & Hardy and Fawlty Towers (1975) bumbling waiter Manuel.

"Ireland's largest lingerie department" in Father Ted: A Christmassy Ted (1996) is in fact Dunnes Stores in Ennis. The sequence was filmed just before the shopping centre was opened.

Graham Linehan and Arthur Mathews decided that Series 3 was to be the final season, because they had felt there wasn't more they could do with the sitcom and with the characters. This series is generally considered to be the funniest.

The role of Father Ted was originally to go to co-writer Arthur Mathews, but it went to Dermot Morgan after the writers saw an earlier performance of his as the character Father Trendy.

A photo of John Wayne playing the Irish-American character of Sean Thornton from the film The Quiet Man (1952) is often shown hanging on the living room wall of the three priests on Craggy Island.

On the DVD Commentaries, one of the writers says that a Priest once remarked to him: "Ah, you don't know the half of it!"

Arthur Mathews was originally going to play the main character, but lacked acting experience. Then Maurice O'Donoghue, who plays Father Dick Byrne, was considered.

The "Ferrero Rocher gag" pokes fun at a commercial that became something of an icon in 1990s Britain: we see a glitzy party in a beautiful reception room, beautiful women in expensive dresses, dashing men in evening dress. Through the throng we see a uniformed butler - he looks to his master (we presume) who nods. The butler then carries a silver salve loaded with a pyramid of Ferrero Rocher chocolates, which the party guests are invited to share. Widespread approval among the guests, one of whom says to the butler's master: "Ambassador, with these Ferrero Rocher you are really spoiling us". Father Ted itself inspired a far less successful advert for the British Government's HM Inland Revenue. In order to promote the Revenue's new self-assessment scheme, Pauline McLynn revisited her role as Mrs. Doyle trying to entice the viewer to go on line to make their tax return - involving her saying "go on, go on, go on, go on....go on line! Go on line, go on line, go on line...." In an opinion poll in the UK it was voted as the most annoying ad of the year.

Graham Norton (Father Noel Furlong) later went on to become a successful television presenter.

Creators and writers Graham Linehan and Arthur Mathews appeared in the sitcom as different characters. Linehan made 2 appearances in the sitcom: Man passing parochial house in Father Ted: Cigarettes and Alcohol and Rollerblading (1996) and Father Gallagher in Father Ted: Flight into Terror (1996). Mathews made 4 appearances in the sitcom: Father Billy Kerrigan in Father Ted: Entertaining Father Stone (1995), Picnic Couple in Father Ted: Old Grey Whistle Theft (1996), Father Ben in The Plague (1996) and Father Clarke in Father Ted: Speed 3 (1998).

In S2 E6 (Plague), Bishop Brennan phones Father Ted from the bathtub. Hanging above the bath is a copy of the Velazquez portrait of Pope Innocent X (1650), with the face changed to that of Bishop Brennan himself.

In Father Ted: The Passion of Saint Tibulus (1995), the cinema used for interior and exterior shots was the Ormonde cinema in Greystones, Co Wicklow.

To celebrate the 25 th anniversary of the show in 2020 the Irish post office An Post has produced 4 stamps with Iconic one-liners from Father Ted. featured on each of the four stamps, is the infamous "That money was just resting in my account", and "That's mad, Ted." "Will you have a cup of tea, Father?", and "That would be an ecumenical matter".

Pauline McLynn declined to appear in the 15th anniversary documentary Small, Far Away: The World of Father Ted (2011).

In the sitcom, Ted, Jack and Dougal are living in exile on Craggy Island which they've all been exiled to by Bishop Brennan: In the backstory behind why all 3 of them were exiled to Craggy Island - Ted was exiled after being under suspicion for stealing child's Lourdes money to fund his own trip to Las Vegas. Dougal was exiled as punishment for unknown misdeeds and Jack's exile was something to do with a wedding ceremony he performed in Athlone.

Dougal has a T-shirt that says "It's a Priest thing, you wouldn't understand".

Frank Kelly and Pauline McLynn had both previously starred in the soap operas Emmerdale Farm (1972) and EastEnders (1985).

In Ireland, even though the country has a majority of the population self-identifying as Roman Catholic, the show is still popular with the "Protestant" population, and a surprisingly large number of both Roman Catholic, and Protestant, priests and clergy.

The series was written and produced in the mid-1990s, before the full extent of Ireland's Roman Catholic Church's various abuse and other related activities became fully known over the following decades. This gives the series a never intended very dark undertone throughout the run. Additionally, its unconfirmed if any of the writers and/or cast regret doing the show, after the revelations gradually came out.

Bishop Brennan is the sitcom's main antagonist due to his hatred and negativity towards Ted, Dougal and Jack whom he hates with a passion and for his abuse of power.

Father Ted: Speed 3 (1998) is a parody of Speed (1994).

Father Ted: Kicking Bishop Brennan Up The Arse (1998) (TV Episode) has Bishop Brennan (Jim Norton) returning later in the episode to Craggy Island, when he realises to his fury, that Father Ted (Dermot Morgan) did kick him up the arse. As part of his confrontation he says, "Try to deny it and I will have you fed, to the dogs!" Norton starred in Straw Dogs (1971).

Michael Redmond playing Father Stone appears in a Brass Eye (1997), playing another priest.

Father Ted is a crazy Irish sitcom that aired from 1995 - 1998 and was broadcast on Channel Four in the Unite Kingdom. Father Ted starred Dermot Morgan stars as Father Ted Crilly, a middle aged hapless priest who is banished by the corrupt Bishop Len Brennan (Jim Norton) to Craggy Island, a fictional island off the coast of Ireland which he struggles to keep the 2 other banished priests who he lives with: the elderly evil drunk Father Jack Hackett and the idiotic young Father Dougal McGuire out of trouble and make his own life work which they would get served cups of tea by their loyal enthusiastic housekeeper Mrs. Doyle (Pauline McLynn).

Father Ted: Speed 3 (1998) is a parody of Speed (1994). Ardal O'Hanlon later appeared with Dennis Hopper who played the main antagonist in that film on The Graham Norton Show (2007). Graham Norton played Father Noel Furlong.

Throughout the show, Ted frequently suffers abuse from Jack and some other characters.

Bishop Len Brennan is the main antagonist.

It's never revealed why Bishop Brennan exiled Dougal to Craggy Island. In one episode, Bishop Brennan mentions that Dougal was punished for an incident at Blackrock aboard a Sealink ferry which the lives of a group of nuns were left irreparably damaged. It's likely that could be the reason why Dougal was exiled.

It's revealed Bishop Len Brennan (who despises Father Ted) exiled Ted to Craggy Island when Ted was investigated under suspicion for stealing child's Lourdes money to fund his own trip to Las Vegas which Ted claimed that the money was resting in his account. There's a theory that Ted could had been set up by Bishop Brennan so Bishop Brennan could have Ted exiled to Craggy Island and Bishop Brennan may had stole the money himself and somehow gained access into Ted's bank account and transferred the child's Lourde money into Ted's account and have Ted framed for stealing the money. Bishop Brennan is known for abusing his power.

In Father Ted: Good Luck, Father Ted (1995) Ted and Dougal visit a fortune teller which Ted has a tarot reading which the fortune teller produces 3 death cards. This creepily predicted Dermot Morgan's death on February 28th 1998 which he died at the age of 45 from a heart attack after production on the 3rd and final season of Father Ted was completed.

Dougal listening to the BBC sound effects album at the beginning of Father Ted: Chirpy Burpy Cheap Sheep (1998) (TV Episode) foreshadows Fargo Boyle being exposed as the mastermind behind sabotaging Chris the Sheep to increase the odds of his victory which it is revealed he used an album of BBC Sound Effects to frighten Chris the Sheep at the end of the episode.
