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 has noticed that it gives a special mark to the project, so he decided to take more control of his series too.

In episodes, Sucker Punch (Season 2, Episode 7), Rewind (Season 2, Episode 8) and (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.

Many critics have referenced the gradual change in profanity levels throughout the series' progression. The first season used terms like "sh**t" and "goddamn" sparcely, 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.

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

The sharp suits worn by Harvey Specter 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.

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

The miniature bike Harvey 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 Louis Litt was awarded the Order of the Coif from Harvard University, Harvard does not have an Order of the Coif chapter making it impossible for Louis to obtain such an honor.

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

Louis discovers that Mike did not attend Harvard because he did not recognize Louis's Order of the Coif key. However, in real life, Harvard does not have a chapter in the Order of the Coif, so Louis could not have received this honor.

The act of Louis Litt talking to his assistant Norma, despite not showing her character even once, is inspired by the character FBI agent Dale Cooper in the TV series Twin Peaks (1990).

Louis Litt officialy "litt up" sixteen people in the first four seasons.

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.
