Grumpy Harrison Ford Roles: Martin Stett 10

<a target="_blank" href="http://www.askmen.com/celebs/men/entertainment/48_george_lucas.html">George Lucas</a> may have been the '70s filmmaker who made Harrison Ford a star, but it was his buddy <a target="_blank" href="http://www.askmen.com/celebs/men/entertainment/francis-ford-coppola/">Francis Ford Coppola</a> who first tapped the actor’s grumpy potential. After Ford broke out as a wise-talking street racer in Lucas’ American Graffiti, Coppola used him as a bitter/creepy businessman in his '70s paranoia classic, The Conversation. Few actors have ever been so unnerving through sheer grumpiness as Ford managed here in a small role. His future clearly wasn’t in playing villains, but Coppola proved that Ford had a knack for intimidation and seriousness.
