Stephen Hawking wants to play a Bond villain.

The 72-year-old scientist and author - who has made a number of on-screen cameos in the past - has confessed his ''ideal'' role would be playing ''a baddie in a James Bond film''.

The wheelchair-bound physicist believes his computerised voice - through which he has communicated since becoming almost entirely paralysed by motor neuron disease - makes him perfect for the part.

He told Wired magazine: ''My ideal role would be a baddie in a James Bond film.

''I think the wheelchair and the computer voice would fit the part.''

Hawking - who is the subject of the upcoming biopic 'The Theory of Everything' starring Eddie Redmayne - appeared in 'Monty Python Live (Mostly): One Down, Five To Go' over the summer while the comedy troupe performed at the O2 Arena in London.

Monty Python star Eric Idle said it was a ''lovely'' experience starring alongside Hawking in the show.

He told Rolling Stone: ''In some of the outtakes, I'm playing [Hawking] the 'Galaxy Song' and I keep making him smile; it's lovely.

''It's not easy to make him smile because he doesn't have much range of movement, but I see his mouth go up and it's just great.''
