Keiko Agena (Lane Kim) was 26 playing a 15 year old in Season 1.

Scott Patterson, who plays Luke, was not originally hired to be a series regular. He was only signed on for the pilot episode, but it was only after the discovery of the undeniable chemistry between him and Lauren Graham that he was contracted for more episodes, and quickly became a series regular.

Liza Weil originally tested for the role of Rory and did not get the part, but the producers liked her so much that they wrote her the role of Paris Geller.

Milo Ventimiglia and Alexis Bledel (Jess and Rory) actually dated in real life for three and a half years.

The set of Stars Hollow is often seen as Rosewood on Pretty Little Liars and Riverdale on Riverdale.

Rory occasionally speaks Spanish with Ezsperanza, where she's shown to be moderately-fluent, using basic conversational phrases. Ironically, Alexis Bledel is Hispanic (of Argentinian descent) and speaks Spanish fluently, having grown up in a Spanish-speaking household. Bledel has stated that her second language was English and she did not learn it until she attended school.

The character of Lane Kim is based on Helen Pai, a co-producer of the show and the best friend of creator Amy Sherman-Palladino.

Luke's character was originally written to be played by a woman, but the producers figured that "there wasn't enough testosterone" in the series and that resulted in Scott Patterson turning the character around.

Because of the unusually longer scripts to fill in fast-paced dialogue, the actors could not improvise or ad-lib any of their dialogue.

In the season 5 opener "Say Goodbye to Daisy Miller", when Luke is leaving Lorelai messages on her answering machine, he states his phone number is (860) 294-1986. This number was used as a bid for donations toward the new Children's and Maternal Hospital at Hopkins to which the number belongs.

The town of Stars Hollow is based on Washington Depot, Connecticut. Creator Amy Sherman-Palladino stayed there while on a trip with her husband to look at Mark Twain's wallpaper.

Lane's father lives with Lane and her mother, but never appears in the show.

Due to the fast pace speech in the show, the average script for an episode of the show runs 75-80 pages, as opposed to 45-50 for a standard hour-long television show. During the 101st episode, a black and white movie from the 1930s is being shown. Lorelai looks at the movie and says they "talked fast" in those movies.

Logan's very wealthy family runs a venerable publishing empire. Their last name, Huntzberger, is a reference to the Sulzberger family, who have owned The New York Times since Arthur Hays Sulzberger succeeded his father-in-law Adolph S. Ochs as publisher in 1935.

Jackson Douglas, who played Jackson Belleville, directed 3 episodes and Lauren Graham produced 11 episodes.

In almost every episode, the episode title is said by one of the characters.

In real life, Sookie's house is actually the backside of Lorelai's house. They are the same house. They make a nod to this in S3E1 "Lazy-Hazy-Crazy-Days" when Lorelai shows Rory a "shortcut" from their house to Sookie's.

Lorelai and Rory's house bears a remarkable resemblance to Lorelai's childhood doll house, which is said to be one of the few things Lorelai cherished from her upbringing.

During a June 2015 cast reunion on "The Today Show," Alexis Bledel was asked if she thought Rory would now be with Dean, Jess, or Logan, and her answer was "none of the above": "I think she'd be seeing someone new, or she'd be single and focused on her career. I don't think she'd be married." Lauren Graham then interjected, "that's the best answer ever!"

After casting Liz Torres as Miss Patty, the producers were convinced they had to cast Sally Struthers due to their presence together in All in the Family (1971).

Sean Gunn, who plays Kirk, made his first appearance in episode 1.2 ("The Lorelais' First Day at Chilton"), but not as Kirk. His character was named "Mick" and he was installing a DSL line at the Lorelais' home that was ordered by Emily.

The character of Jess (played by Milo Ventimiglia) was supposed to have a spin-off called "Windward Circle" which was picked up by the WB for midseason 2004, in which the character moves in with his estranged father (played by Rob Estes) and his father's girlfriend (played by Sherilyn Fenn) from Connecticut to California. But due to the high cost of filming on location in Venice, California, the WB changed their minds and decided not to go forward with it.

The girl who played the younger Lorelai in season 3 had to wear blue contacts due to her natural eye color being brown. As a result, it made her eyes look purple.

The number of years that Richard and Emily have been married changes. In S2E3 it's 34yrs, S5E13 it's been 40yrs. In episode 18 of season 2 they have been married 35yrs, that's also how long Richard has been in the business world, yet in episode 6 he tells Dean 30 years.

Seasons 4-7 were filmed and aired in HD widescreen. The DVDs were released in the cropped full screen format however, reportedly because Amy Sherman-Palladino didn't like widescreen.
