Russell Johnson, who played Professor Roy Hinkley on Gilligan's Island, has passed away at age 89.
Johnson was a busy but little-known character actor when he was cast in the slapstick 1960s comedy about seven people marooned on an uncharted Pacific island.
His character, high school science teacher Roy Hinkley, built generators and other gadgets out of scraps of junk found on the island. Johnson later joked that the one thing The Professor never figured out how to do was to fix the leaky boat so the group could get back to civilization.
