Dame Helen Mirren would like to see a film all about James Bond character M.

The Oscar-winning actress thinks it would be "cool" to see Dame Judi Dench reprise her role as the British spy boss in a spin-off of the franchise with the leading female part.

She said: "That would be cool! Sort of - what's Dame Judi's character in Bond? M! - yes sort of a movie all about M would be great."

Helen - who also played an assassin in action movie 'Red', and won an Oscar for her performance as Britain's Queen Elizabeth II in 'The Queen' - has previously claimed female spy roles are "undervalued" and believes more films should star them.

She said: "I'm going to play a spy a little bit. It's kind of interesting.

"The role of women has always been undervalued in the spy world, always undermined in terms of recognition. It's a world that needs women."
