Although the cause of death Tuesday wasn't immediately reported, E! News quoted a woman identified as his sister as saying he hit his head in a fall. The woman's name was not reported.
Shadix, who lately used a wheelchair, is perhaps best known for his big-screen collaborations with filmmaker Tim Burton on "Beetlejuice," "Planet of the Apes" and "The Nightmare Before Christmas." He also appeared on the TV shows "Carnivale," "Seinfeld," "ER" and "Sabrina, the Teenage Witch."
E! News said his funeral is set for Saturday in Birmingham.
