Trivia: Director Eli Roth wanted to use the same child actors for the "Bubblegum gang" that were in the first film. While he was able to use some of them (including the "lead" member), a number of the child actors had began to have growth-spurts in between films and no longer looked the same, and thus had to be recast.
Trivia: When Beth finds the room with the severed heads, watch the screen closely. The severed head to the left of Paxton's is actually director Eli Roth's head. Roth had the makeup-effects department build severed-head prop made of himself for this grisly cameo. (And contrary to popular belief, Roth confirmed that producer Quentin Tarantino's head is NOT in the scene.).
Trivia: The woman who bathes in the blood of one of the lead characters was inspired by the story of Countess Elizabeth Bathory, a female serial killer who lived from 1560-1614. She was accused or torturing and killing numerous victims, and her crimes lead to the creation of a false myth that she would bathe in the blood of her victims in order to maintain a youthful look.
