When John Ritter's character is killed, his face looks like Pinhead from Hellraiser. Chucky exclaims "Where have I seen that before?"
A certain Bride of Chucky promotional poster is a parody of one of the Scream 2 posters.
During the end credits, we hear Tiffany say "We belong dead", and at the end of the credits, after a rock'n roll song is played, Chucky says "That's more like it", followed by his laughter.
