Actress Isla Fisher feels unworthy of her status as a rising Hollywood star, blaming her insecurities on her Australian background.

After impressing with her role in Wedding Crashers, the pregnant partner of Borat star Sacha Baron Cohen has landed a number of follow-on movie parts - and she is still coming to terms with her success.

The 31-year-old former soap star says, "Maybe it's an Australian thing but I always feel that I shouldn't be here somehow. When I'm auditioning for films with women I really respect, and usually when they get the job and I don't, I just think, 'Well, they really deserve it'. I feel a bit of an interloper."
