What actor appeared in a movie with George Reeves and in another one with Dan Aykroyd? Email your answer to EMAIL REMOVED FOR PRIVACY

Why should people reveal their e-mail to you when they can just reply to this thread. We do not permit this type of action here.

How about one of you experts answering the question??
