Okay this may or may not be a bit too obscure...if so speak up and I'll try to come up with something else.

This National Football League Hall of Fame running back (American football for those of you overseas) got his first movie role in the 1976 movie, Midway portraying Cmdr Delaney, the engineering officer aboard the USS Yorktown. Who was this man?
