Where Did They Go?

So I'm watching Chelsea Handler's talk show right now, and I see Scott Thompson on her panel when they talk about celebrity news. And I'm thinking "god, I haven't seen that guy in a long time." :p

So now, I'm trying to think of some other celebrities that I haven't seen recently, but that years ago were rather popular.

Who are some celebrities that you've either seen recently after a long hiatus of not hearing about them, or some celebrities that you liked and have no idea where they are now?

Where the smurf a Mel Brooks & Gene Wilder?
