Daily Dish Cameras can be tools for peace. Mickey Rourke and Oliver Stone got into a heated argument the other night at L.A.’s Berman/Turner Gallery – that is, until they realized someone was filming them. Hoping to head off an item like this, the veteran bad boys found a photographer to shoot them smiling and shaking hands. Also trying to behave at the exhibit (sponsored by The Erotic Network) of Timothy Greenfield-Sanders’ “XXX: 30 Porn-Star Portraits” were Gore Vidal, Kelly Lynch, Owen Wilson and hard-core hardbodies like Tera Patrick, Nina Hartley and Sean Michaels.
