January Jones has ruled out ever portraying Grace Kelly in a movie biopic - she's convinced it would destroy her career.
The actress has frequently been compared to the legendary Hollywood beauty but she's determined never to step into her shoes for a film role, because Kelly is too well known to movie fans.
Jones tells Britain's The Times, "I've been offered a couple of TV movies playing Grace Kelly and there was no way I would touch them with a seven foot pole.
"It would be career suicide. No one would watch them and come away saying anything other than, 'She's so not Grace Kelly.'
"Cate Blanchett got it right as Katharine Hepburn, but generally it doesn't matter how much you look like that person or how good an actor you are, it's impossible."
The actress turns her hand to the big budget blockbuster this summer when she takes on the role of Emma Frost in X-Men: First Class.
She can currently be seen on the big screen in Unknown, in which she stars alongside Liam Neeson.
