Weirdo

So one of my favorite bad guy actors is Brad Dourif. You won't recognize the name, but he's in TONS of stuff as the creepo. He really takes the cake. He's been in over 100 films and TV shows since the mid 1970's, as a bad guy in almost all of them (and a super creepy one at that) such as...

Law and Order (2008)
Deadwood (2004-2006)
Lord of the Rings: Return of the King- creepy sidekick to that king (2003)
Lord of the Rings: The Two Towers (2002)
SNL- as Chucky (1998)
Bride of Chucky- voice of Chucky (1998)
Urban Legend- creepy gas station guy
Alien: Resurrection (1997)
Star Trek: Voyager- serial killer crew member in 3 episodes (1996)
Babylon 5- a monk who was a serial killer before being reprogrammed with new memories (1995)
Escape to Witch Mountain- a chauffeur [it was Disney, first time i ever saw him] (1995)
The X-Files- serial killer that channeled the dead [most recent thing i saw him in and for which he received an Emmy nomination] (1994)
The Exorcist III- the Gemini killer (1990)
Murder, She Wrote- [episode called: Fire Burn, Cauldron Bubble- i.e. only truly creepy episode of the 70 year old Jessica Lansbury series] (1989)
Miami Vice (1987)
Moonlighting- as Father McDonovan [has a thing for creepy and priesthood] (1986)
Spenser: for Hire (1986)
Dune (1984)
Rag Time (1981)
One Flew Over the Cuckoo's Nest- Billy Bibbit [Golden Globe] (1975)

Also, he was apparently cast as the Scarecrow for Batman Forever when Tim Burton was attached to the film and was replaced by Tommy Lee Jones and Jim Carey as Two-Face and the Riddler. And we all know how that turned out...

But Dourif has other skills outside screen and stage. He appeared in the music video Stranger in Town by Toto. Also, he plays the didgeridoo and is on a CD called: Eating Jello With a Heated Fork
