She may be one of Hollywood's hottest actresses, but Scarlett Johansson fears her career has peaked too early.
The 21-year-old, who starred in her first film at the age of 12, worries that every film she makes will be her last - despite having had criritcal and commercial success with films such as Lost In Translation and The Black Dahlia.
Scarlett said: "Do I ever get nervous about this, right now, being the pinnacle of my career? Yeah I do. At the end of every movie I think 'Wow - this is the last one! Nice working with you.'"
Well, it's nice to know even mega-stars have their moments... |
