I just read an article on him -- his name is Sacha Baron Cohen (and plays Ali G. and Borat). His new movie is called "Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan".
It sounds pretty fucking funny -- some of the scenes apparently include "The running of the Jew", Borat leading a bar full of country fans in a song called "Throw the Jew down the Well", and Borat on a date telling the woman she reminds him of his dead wife. Oh, and Sacha Baron Cohen is a Jew.
