Frequently makes uncredited appearances in his own movies. Originally, Donner directed Superman (1978) and Superman II (1980) back to back, then cut back on filming the sequel to focus on finishing the first one for a Christmas release. A clash with the producers, the Salkinds, over the material led to Donner being fired before he could finish filming the second one and he was replaced with Richard Lester. Donner later estimated that he had directed 80% of the sequel and saw about 50% of his work in the theatrical film. Kept both One-Eyed Willie's head and a model for the ship from The Goonies. Aside from directing the film , he has an uncredited cameo as one of the sheriffs on the quads as the Goonies exit the cave with the ship. He's the one with the gray hair. Producer Steven Spielberg instructed the cast members to act cold and distant toward Donner on the last week of filming which puzzled him. Shortly after filming wrapped, Donner went to his beach house in Hawaii, ran into a frenzied neighbor who took up his entire day. When he arrived home, the entire cast was there with Donner to celebrate with a cookout. Spielberg flew them over to Hawaii on the promise that they not speak a word of the surprise to Donner, which prompted them to act the way they were on the last week of filming. Actor Steve Kahan is his cousin. Kahan has appeared in 12 of his movies.
