George Clooney brought political controversy to Venice on Thursday with "Good Night. And, Good Luck," a black-and-white tale of broadcasting courage during the McCarthy-era witch hunts of the 1950s. Clooney, who acts in and directs the film, is the first of several A-list Hollywood stars due to walk the red carpet at the sun-soaked Lido, host to days of waterfront parties. Clara Ferreira-Marques reports in Reuters.
