Throughout the movie the Olympics are only implied. The word "Olympics" and the Olympic symbol are not actually in the film due to strict control by the Olympic Committee.
Real-life Olympic gymnast and medalist, Dominique Moceanu, has a cameo is the film. While she is not a native Ohioan, Moceanu has lived in Northeast Ohio much of her adult life and currently resides in the Cleveland area. The film is set in Amherst, which is a suburb of Cleveland.
All of the eatery locations in the film are real places (Hastee Tastee, Quarry Cafe, Midway Mall food court). Hope's house is on the small street of Brandt Avenue, but the building used for Pavleck's gym (once a pizza parlor) was demolished in 2016.
Melissa Rauch used a body double for the nude sex scene, while Sebastian Stan did the scene himself. Rauch wrote the scene because she felt it would be funny, but refused to be nude herself. She said in an interview "Why should I show my boobs and ass when we can pay some unknown to do it?" She then chose a double that she felt had a much better body than hers. Later she grew frustrated when several porn sites posted the nude scene saying it was actually her.
