Helena Bonham Carter wants to work with other directors.

The 44-year-old actress has collaborated with her long-term partner Tim Burton - with who she has children Billy, seven, and three-year-old Nell - on six movies but believes she would have a more peaceful working experience if she was hired by someone else.

She said: "I am available for work other than with the boyfriend. And I will certainly make it a calmer, easier, happier set to work on."

Helena has been nominated for a Best Supporting Actress Oscar for 'The King's Speech' - which she stars in with Colin Firth and Geoffrey Rush - and though she thinks she is undeserving of the accolade, she is grateful people have been able to see her in a conventional role.

She admitted: "I feel like I'm flying on their coattails. But it is good for me to be seen as vaguely normal in a film instead of being dressed as a witch or some strange character."
