For a few months, following the release of Rocky IV, a joke was making rounds in Hollywood. Since Rocky Balboa had run out of earthly opponents, he would have to fight an alien if a fifth installment of his boxing series were to be made. Screenwriters Jim and John Thomas took the joke seriously and wrote a screenplay based on the joke. The Thomas script for Predator was originally titled Hunter. It was picked up by 20th Century Fox in 1985, and turned over to producer Joel Silver who, based on his experience with Commando, seemed the right choice to turn the vintage science fiction pulp storyline into a big-budget film. Silver enlisted his former boss Lawrence Gordon as co-producer and John McTiernan was hired as director for his first studio film.
