Here's an actor i wonder could've played corky

Donald Sutherland. The same year this film came out was the remake of INVASION OF THE BODYSNATCHERS. The next year when it came on showtime i was a little kid and [SPOILER ALERT[ the end when Sutherland's character has shown to be duplicated as he's pointing his finger giving a wailing scream scared me. He has a distinct look to him and they would probably make fats to look like him if he was cast.
