Alison Brie, a self-professed nudist and exhibitionist, used her personal experiences with public nudity in the writing and incorporated them into her character. She told the Hollywood Reporter that, "I had a real penchant for streaking in my college years. I kind of took a step away from that, but, in more recent years, I've gotten back into it."
The "this is my note" scene between Alison Brie and Danny Pudi is a reference to their Community (2009) co-star Jim Rash, who would do it as a warm-up.
In an attempt to quell husband Dave Franco's nerves ahead of the premiere of the movie, practicing nudist Alison Brie ran totally naked through the halls of a Los Angeles hotel they were staying at and knocked on their room door. When Franco opened the door to discover his nude wife, he just smiled, unfazed, and said "Get out of the hall." To which Brie replied, "I've done three laps already!" Brie had a friend capture the moment on video and posted a censored version on her Instagram account.
The role of Benny was specifically written with Danny Pudi in mind to capitalise in his real-life friendship and acting chemistry with co-star Alison Brie.
