I can't remember his name, but the actor that played Tom Cruise's Navy captian in Top Gun.
Sly, Cool and Tough. Much like Yul Brynner.
James Tolkan

I like him in all the movies I've ever seen him in. He was in the Back to the Future Trilogy too, right?
I think he was the principal. Remember when Marty went back in time and saw him and asked, "Did he ever have hair?" 
That was him!
