OCEAN'S TWELVE producer Jerry Weintraub is so determined to make his actors feel comfortable, he insists they treat his plush residence in Palm Desert, California, as their own home. The hospitable movie-maker claims Brad Pitt, Matt Damon and Catherine Zeta Jones often stay over with him, and George Clooney even has his own suite. He says, "If we're going to spend six or eight months together, it's best that we get along well. "I'm your pal. This house, it's my house and it's also their house. "Matt and Catherine have stayed here. George has his own suite and Brad shows up every once in a while on the weekend."
