Sketchbook➝Famous Faces - Part III

This is the third part in my on-going attempts at capturing a likeness. Parts one and two were in pencil, this time I decided to digitally paint them. I thought I'd try make them a little harder, too. I think these people are either a little less distinctive or a little less well known. Also, no clues at all this time!

So, can you tell who the following three famous faces are?
