Diaz walks green carpet in Sydney

Hollywood glamour girl Cameron Diaz walked a green carpet in Sydney tonight to launch Shrek The Third, the latest in one of the most successful film franchises of all time.

She joined her on-screen husband, the much-loved green ogre himself, and the chief executive of DreamWorks Animation SKG Jeffrey Katzenberg, to promote the film which opens here nationally on June 7 but has already smashed box office records in the United States.

"It's fantastic, we couldn't be more happy," Diaz said of the film's early success after its opening weekend.

Diaz, dressed in a slight strapless dress on a chilly Sydney evening, stopped traffic passing the State Theatre twice to greet waiting fans and sign autographs.

After this weekend the film holds the record for the biggest first weekend takings for an animated feature film and has earned the third highest opening weekend income for any film when it brought in $US122 million ($149 million).
