The House

Mariah Carey was scheduled to film a cameo but her scenes were never filmed. Will Ferrell recalled that she showed up four hours late, then didn't want to do the scene she had agreed to do. She then delayed production by not wanting 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 lambs. Carey's scene was ultimately not filmed.

When Scott has trouble recalling the combination to the safe, Kate encourages him by saying that he can remember 4 sequential numbers. When Scott does remember the combination it is 8 numbers plus #. Then the combination punched in to open the safe beeps 7 times, which means only 6 numbers were entered with the # sign.

After the last scene and before the credits start rolling, there is a series of blooper scenes from different cast members.
