Voted by the AFI as the best actor of the last century. Tracy's best films are any films that he made quite frankly, although in my mind the comedies stand out, especially those with Katharine Hepburn Desk Set and Pat and Mike, as well as comedies like Father of the Bride.

Essential Films:

San Francisco
Captains Courageous
Young Tom Edison
Edison the Man
Boom Town
Keeper of the Flame
A Guy Named Joe
Without Love
Father of the Bride
Father's Little Dividend
