British movie star Rachel Weisz was stunned when her new movie The Fountain was booed at its premiere at the Venice Film Festival yesterday. The film, directed by her fiance Darren Aronofsky, left the audience confused and disappointed - even though Weisz insists it is important to have something "different" on screen. The $35 million flop was snubbed repeatedly by movie studios until Warner Brothers decided to back it. The story spans 1,000 years and stars Hugh Jackman as a 16th century Spanish explorer, 21st century scientist and 26th century astronaut searching for the Fountain of Youth. Weisz, whose presence at the festival marked her first official public appearance since the birth of son Henry Chance in May, says, "I think it's wonderful that this film is so different. I would love to work with Darren again."
