Bradley is known throughout the realm of Horrorland as "the guy who played Pinhead in the brilliant Hellraiser and its gradually lamer series of sequels," while Henriksen is a genre god second only to someone like Bruce Campbell or Joss Whedon. Best known for his performance as the "synthetic human" Bishop in James Cameron's Aliens, Mr. Henriksen has spent much of his career in the horror/sci-fi end of the spectrum. Despite the fact that he's appeared in movies like Dog Day Afternoon, Network, and The Right Stuff, Henriksen's most often recognized as the cop from The Terminator, the daddy vampire from Near Dark, and the cyborg who got ripped in half from Aliens.
Evil Aliens will hit R1 DVD later this year, courtesy of Image Entertainment. Pumpkinhead 3 is currently in production. (And by the way, both Pumpkinhead movies are actually pretty solid. Give 'em a rental if vengeful monsters are your thing.)
