FILM 1748: THE HOUSE
TRIVIA: Amy Poehler and Jason Matzounkas appeared on Parks and Recreation (2009).
Mariah Carey was scheduled to film a cameo. However, her scenes were never filmed. Will Ferrell recalled that Carey showed up four hours late, then didn't want to do the scene she had agreed to do. Carey then delayed production, as she didn't want to sing the song, one of her own, that she was supposed to sing. This would have required the legal department to clear the song. Carey also required her trailer to be filled with white flowers and stuffed animals of lambs. Carey's scene was ultimately not filmed.
Amy Poehler and Nick Kroll were a couple from 2013 to 2015.
