There is a character in the film named Damien Baylock. In The Omen, the satanic child is called Damien, while his evil nanny is called Mrs. Baylock.
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.
