OCEAN'S THIRTEEN co-stars George Clooney, Brad Pitt and Matt Damon left their handprints in cement outside the Chinese Theater in Hollywood yesterday (05Jun07). The three actors and Ocean's Thirteen producer Jerry Weintraub made their mark near where the stars of the original Ocean's 11, Frank Sinatra and Dean Martin, left theirs in the early 1960s. Clooney told the crowd, "If I had to be on my hands and knees with three other guys I can't think of three better guys to do it with."
