Watts has been wowing blockbusting crowds across the world, with a little help from a giant ape, and has apparently impressed producers of the James Bond films, who are looking to find a female foil to go up against Daniel Craig in his inaugural outing as the dapper secret agent.

Convincing as a strong yet vulnerable heroine playing Ann Darrow in Lord of the Rings director Peter Jackson's re-imagining of the Kong classic, Watts would be required to take on a slyer, more steely role if she accepted a part in Casino Royale.

Producers have apparently already made phone calls to Watts' representatives, urging her to take on the role of Russian vixen Vesper Lynd, Bond's female love-nemesis for the film.

However, sources close to the Australian actress claim she might turn down the role for fear of type-casting herself.

Having said this, other Bond girl actresses haven't experienced such problems – see Halle Berry, Teri Hatcher and Honor Blackman.

The hotly sought after part has reportedly already been turned down by a number of Hollywood A-listers, including Oscar-winner Charlize Theron and Angelina Jolie.

Jolie clearly has no qualms about type-casting, after rumours emerged that she would be playing Lara Croft in a third Tomb Raider film.
