Witchcraft in the movies

I have been doing some research into witchcraft films and watching my fair share of horror's, one in particular that i found inspiring is called "The Lords Of Salem" and its directed by Rob Zombie who also directs a film which i love called "House of a Thousand Corpse's". The Lords of Salem is based around a girl who lives in this flat and little to her knowledge after hearing a record played on her radio show, the three old women in her building are satanic worshipers and they make her become one of them. The movie flicks from present time to back in time to the Salem witch trails. I thought of using aspects from the lead girl toward Claudia, but how in her case she has been willing taken over by satanic worshiping and  witchcraft.
