British actor Daniel Craig has urged Sienna Miller not to quit acting, because her talent is too great to waste.

Craig, who co-starred with Miller in Layer Cake, was horrified when he learned how intense press attention during her split from adulterous fiance Jude Law caused her to reconsider her career - and he insists losing her from the silver screen would be a travesty.

He says, "Sienna is special, she has chutzpah (audacity).

"I've heard she's considering giving up because of the pressure - but this is one artist that shouldn't."
