!!This actor provides examples of the following tropes:

* CreatorCouple: With his wife Creator/MaggieGyllenhaal. The two performed in ''Theatre/UncleVanya'' and ''Theatre/ThreeSisters'' on stage together.
* SheCleansUpNicely: Male version. He's capable of ping-ponging all over the attractiveness spectrum depending on the role, and can look ''very'' dapper when the situation calls for it, as the image above shows.
* StarMakingRole: ''Film/ShatteredGlass''.
