"The Da Vinci Code" may have fizzled with critics at Cannes, but the second major Hollywood movie to sweep into the festival, "Dreamgirls," cast a spell over audiences that led to early Oscar buzz. Movie studios Paramount Pictures and DreamWorks showed 20 minutes of their film, which is set for a December release, to a standing room only crowd late on Friday night at a side venue at the world's largest gathering of movie makers and stars. U.S. pop singer Beyonce Knowles and Oscar-winning actor Jamie Foxx, who star in "Dreamgirls," were on hand, as were major celebrities like Bruce Willis, Hugh Jackman and Britain's Sir Ian McKellen.
