According to an interview with director John McTiernan, the "hole in the jungle" appearance of the Predator was played by Jean-Claude Van Damme in a "blue screen" (actually red) suit. Van Damme quit after two days, unhappy with being cast as an uncredited special effect. The alien was scrapped, redesigned and was eventually played by 7'2" Kevin Peter Hall. Sonny Landham was hired to work on this film, but on one condition: the insurance company insisted on a round-the-clock bodyguard for Landham, not to protect the actor, but to protect everyone else from the actor (who was prone to bar fights, etc.). An attempt was made to get shots of the Predator swinging from tree to tree using a monkey in a red special-effects suit. However, the monkey kept removing the suit and the idea was abandoned.
