Yes He was in Predator,but he gets kill to early in the movie and I guess after that he like writting better.He's a great writer.Students at USC film school had told me he's one of the best.I know for a fact that he is a cool guy .Check KIss ,Kiss Bam Bam I like that one He wrote it and Directed it.

Is the writer Shane Black who wrote Lethal Weapon and The Last Action Hero the same person as the actor in The Predator?
