When the show first began filming in Toronto, Macht did not have a place to stay, so Adams (being Canadian) let Macht stay in his mother’s penthouse. The two lived together for 10 days.
When Louis holds his trivia game, Seth claims that five Supreme Court judges attended Harvard. Mike claims correctly that there were six. This info is from the pilot: Mike learns it during his tour of Harvard, in a guidebook.
When Mike tells Harvey that Louis knows the “dirty little secret” (that he didn’t go to law school), Harvey flippantly responds with “You’re Canadian?” It’s a subtle bit of irony, Adams is actually Canadian.
Meghan Markle is a foodie in real life, which is the inspiration for her character Rachel’s obsession with food in Suits. Markle’s Instagram account is full of her food adventures, as well as her adventures as a Global Ambassador for World Vision Canada
A recently announced possible spinoff of Suits was pitched by Gina Torres and will focus on her character Jessica Pearson as she brings her legal expertise to Chicago politics.
Louis Litt invented and even trademarks the term “Litt up,” which he explains means to dominate someone else through wit, power, and intelligence. Louis “lit up” 16 people in the first four seasons.
Harvard doesn’t have an Order of the Coif (though other law schools do), so Mike not recognizing it is not actually proof that he didn’t go to Harvard. Louis also mispronounces Coif as “kwaff”; lawyers actually pronounce it “off.”
Macht doesn’t have to look far to research his role as one of New York’s most powerful lawyers. Numerous members of his family, including his sister, aunt, and cousin, are lawyers, and his grandfather was a judge.
Louis Litt may be the office cat guy, even going so far as to bring one to the office with him, but Rick Hoffman, who plays Louis, is severely allergic to cats. EpiPens and inhalers are close by whenever he has to interact with them
While the show takes place in New York City, Suits is actually filmed in the city of Toronto, Canada. The move was made to take advantage of the generous tax credits offered by the government of Ontario.
