Funny People in Serious Movies

A lot of times a Comedian or Comedic Actor will take a dramatic role in a serious drama and usually turn in a fine performance. Already, this year is no exception. (Can’t name the film here but it is on the list.) Which is the best film featuring a Comedian or Comedic Actor in a dramatic role?

No joke, you can get serious about the subject here. The sad part here is that many listed here are listed as comedies. But as you watch them, you quickly realize they are not comedies but either romances or light comedy / drama mixes.
