Jason Sudeikis stated in an interview that they wanted to put a gag in the film, where Jamie Foxx's character says to Nick, Kurt, and Dale, "You crackers got to go. I have three other crackers coming in," and as the trio get up to leave, the three characters from The Hangover movies would come in and sit at the booth. They finally decided against it, because it would take the audience out of the movie. Zach Galifianakis and Ed Helms (Alan and Stu from The Hangover films) later heard about this, and thought the idea was hilarious.
The name Nick gives to Julia, Blanston, is an homage to a Steve Martin stand-up bit where he claimed his real name was Gern Blanston.
The cast has a total of five Academy Award winners: Jamie Foxx (Ray (2004)), two from Kevin Spacey (The Usual Suspects (1995), American Beauty (1999)) and Christoph Waltz (Inglourious Basterds (2009), Django Unchained (2012)).
