The merchandising people came up with some Jack Slater action figures with guns. Arnold Schwarzenegger vetoed the idea because this movie was a warmer, more cuddly action movie. Merchandising included seven video games, a $20 million Burger King promotion, a $36 million theme park ride, N.A.S.A.'s first paid ad in space, and a four-story inflatable Jack Slater at Cannes. Schwarzenegger gave forty television interviews and fifty-four print interviews in twenty-four hours, setting a new personal record.
