Possibly the best actor of the 20th century, Spencer Tracy let his red-haired persona come out on screen as well in real life.

Tracy had hot romances with many of his leading ladies, drank excessively – on the movie set as well – while garnishing two Best Actor Academy awards. Teaming up with Katharine Hepburn for nine Hollywood onscreen romances, their love carried off the screen for over 25 years even while he was married. Sounds like a wild redhead!
