It's been more than nine years since Christopher Reeve passed away, and ET sat down with the late actor's oldest son to talk about a side of the man that few got to see.
"He was wickedly funny and had a very dry wit," said Christopher's son Matthew Reeve. "I don't think people know that about him. He maintained that humor even after his injury. He was just always a funny guy."
Christopher, famous for his role as Superman, was confined to a wheelchair after a tragic riding accident in 1995.
