Actress Helena Bonham Carter is convinced moviemaker Tim Burton finds her attractive because she is the female double of his longtime pal and collaborator Johnny Depp. The Brit, who is expecting a second child with Burton, insists she and Depp, who co-star in the director's new Sweeney Todd musical, share looks and character traits. She explains, "We have the same frown line and there's certain similarities between the two of us, according to Tim - we always like to camouflage ourselves to the hilt when it comes to playing parts and we both loathe watching ourselves. "And we're both pale and tubercular and have big eyes. Tim's always said we would be great in a silent movie. I think he definitely thinks I should've been in a silent movie because I talk too much."
