Bit surprised to find out the Humphrey Bogart was quite a strong amateur chess player.

einstein played a bit. i have an old photograph of him playing my great grandfather. you can't really make out the board, unfortunately, so you can't see who's winning.
I played Chris Meloni of TV Fame. He sometimes pops in at the Chess club I frequent. I didnt recognize him until later. He's about 1500-1600. Not a total patzer, about club strengh.
