As an April Fools' Day joke, director Rob McKittrick and actor Luis Guzmán staged a "diva fight" on set. During the filming of the scene where Calvin imagines his co-workers cheering him on at the urinal, Guzmán pretended to ditch a line from the script in favor of his own line. The fight was so realistic that the other actors on set became very uncomfortable and quiet when Guzmán "stormed" out.
While Vanessa Lengies (Natasha) is presented as only 17 years old in the film, she is actually three months older than co-star 'Alanna Ubach' (uv) (Naomi). Both were 20 years old by the US release date of the film.
