Stephen Macht (Professor Gerrard) is the real-life father of Gabriel Macht (Harvey Specter). Gabriel Macht's inspiration to become a producer in the series (and take control in areas such as casting department) came when he was watching Whose Line Is It Anyway? (2009), a comedy show where the actor and singer Gustavo Goulart is responsible for many departments at the same time. Macht noticed that it gave a special mark to the project, so he decided to take more control of his series too.

In episodes, Suits: Sucker Punch (2012) (Season 2, Episode 7), Suits: Rewind (2012) (Season 2, Episode 8) and Suits: High Noon (2012) (Season 2, Episode 10), Jacinda Barrett made an appearance as Zoe Lawford. Barrett, in real life, is married to Gabriel Macht, who plays Harvey Specter.

Some of the prints that hang on the wall in Rachel Zane's (Meghan Markle) office in season 3 are the work of Patrick J. Adams (Mike Ross).

BuddyTV rated this series the second-best new show of 2011, one spot behind Game of Thrones (2011).

Gabriel Macht (Harvey Specter) and Sarah Rafferty (Donna Paulsen) are best friends in real life. They have known each other for almost 20 years and Macht is the one who suggested her for the role of Harvey's loyal and faithful assistant.

Patrick J. Adams (Mike) and Troian Bellisario (Claire) got married on Saturday 10th December 2016.

Meghan Markle (Rachel Zane) and Abigail Spencer (Dana "Scottie" Scott) were both born on August 4, 1981.

Many critics have referenced the gradual change in profanity levels throughout the series' progression. The first season used terms like "sh**t" and "goddamn" sparsely, but still more often than most basic-cable shows. As they became a success, these words were used even more liberally in future seasons. The Season 7 premiere was the first to feature the word "f**k," and since then it has not been uncommon to hear one censored use within the episode.

The role of Jessica (Gina Torres) was originally written as a male character, but both the studio and the network suggested creator Aaron Korsh change the gender.

Although the show is set in New York City, Suits is shot in Toronto, due to tax credits. The pilot was shot in NYC.

The sharp suits worn by Harvey Specter (Gabriel Macht) are the "Windsor" model by American fashion designer Tom Ford. They are characterized by wide peak lapels and a British-style ticket pocket on the jacket. They also occasionally come with a vest/waistcoat to make a three-piece suit.

Harvey's (Gabriel Macht) last name, "Specter," can be scrambled to "respect."

D.B. Woodside and Rachael Harris play Jeff Malone and Sheila Sahz respectively but never share a scene. They also star on Lucifer (2015), where many of their scenes are together.

Both Vanessa Ray and Troian Bellisario have played love interests of Patrick J. Adams (Mike Ross). Although the actresses never shared any scenes on Suits (2011), they had several scenes together on another show, Pretty Little Liars (2010). Adams, who is the real-life fiancé of Bellisario, also appeared on Pretty Little Liars (2010), but he shared no scenes with Bellisario nor Ray.

The favourite show of both Michael Phelps and Charles Barkley. Both expressed their love for the show and were therefore offered roles.

Gabriel Macht (Harvey Specter) and Patrick J. Adams (Mike Ross) made their directorial debuts in Season 4, with Macht directing Episode 11, Suits: Enough Is Enough (2015), and Adams directing Episode 14, Suits: Derailed (2015).

Meghan Markle's full name is Rachel Meghan Markle. Markle plays Rachel on the show.

D.B. Woodside and Gina Torres, who play lovers on this show, also played lovers in another TV series, 24 (2001).

Every Suits (2011) season, except Season 1, contains a flashback episode.

In Season 2, Rachel (Meghan Markle) asks Mike (Patrick J. Adams), "Is it so hard to believe that my father is black?" In real life, Markle's mother is black, not her father.

The building used for the Pearson-Hardman law firm is the same used in Orphan Black (2013) where Sarah Manning (Tatiana Maslany) meets Rachel.

Gabriel Macht's last name coincidentally means "power" in Dutch and German.

References to the TV show Game of Thrones (2011) are made in numerous episodes of Suits (2011). Michelle Fairley and Conleth Hill, who both had parts in Game of Thrones, were guest stars in seasons 2 and 3 of Suits.

The miniature bike Harvey (Gabriel Macht) has in his office is the Brough Superior SS100 (1932), made by Minichamps in 1:6 scale. This was the motorcycle T.E. Lawrence, also known as "Lawrence of Arabia," was riding when he was killed.

Although on the show Rick Hoffman was awarded the Order of the Coif from Harvard University, in real life Harvard does not have an Order of the Coif chapter.

Harvey Specter (Gabriel Macht) received his undergraduate degree from New York University.

Louis (Rick Hoffman) pronounces Order of the Coif in the French way ("kwaff"). However, U.S. lawyers actually say it "koyf."

Amanda Schull (Katrina) was another actor to appear on both Pretty Little Liars (2010) and Suits (2011), along with Troian Bellisario, Vanessa Ray, and Patrick J. Adams. Apart from Adams, she did not share any scenes with Bellisario or Ray in either Suits nor Pretty Little Liars.

The character of Rachel Zane, played by Meghan Markle, was originally to be called Rachel Lane. When it became clear that was too similar to someone's else's name, creator Aaron Korsh renamed the character to Rachel Zane, after casting director Bonnie Zane.

Rick Hoffman played a character in Cellular (2004) similar to his character on this show.

Troian Bellisario (Claire), Amanda Schull (Katrina), Vanessa Ray (Jenny) and Andrea Parker (Tory), who have all played characters on this show, all also appeared in the TV show Pretty Little Liars (2010).

Louis Litt (Rick Hoffman) talking to his never-seen assistant Norma is inspired by the character FBI agent Dale Cooper (Kyle MacLachlan) in the TV series Twin Peaks (1990).

Louis Litt (Rick Hoffman) officially "litt up" sixteen people in the first four seasons.

Following the announcement Meghan Markle (Rachel Zane) was to marry Prince Harry, her onscreen husband, Patrick J. Adams (Mike Ross), posted a playful tweet, "She said she was just going out to get some milk." He later followed it up with, "Playing Meghan's television partner for the better part of a decade uniquely qualifies me to say this: Your Royal Highness, you are a lucky man and I know your long life together will be joyful, productive and hilarious. Meghan, so happy for you, friend. Much love."

Louis (Rick Hoffman) discovers that Mike (Patrick J. Adams) did not attend Harvard because he did not recognize Louis's Order of the Coif key. In real life, Harvard does not have a chapter in the Order of the Coif, so if the show took place in the real world, Louis could not have received this honor.

Following Meghan Markle's engagement to Prince Harry, it was revealed that she had been written out of Suits over a year prior to the announcement. Aaron Korsh, the show's creator, said, "I knew from a year ago that this relationship was burgeoning and I had a decision to make...the only way to write a character out like that would be if they got hit by a bus or something."

The whole view of the city landscape in the background of the main characters' offices are not real. Rather, they are curtains.
