"They always have some disability, don’t they? I could have one leg and be stroking a chicken saying, ’I’ve infected the world with bird flu’," he said.

But the 35-year-old insists he wouldn’t play the dashing spy himself, particularly as hunky Daniel Craig looks as if he’s in for the long haul.

"I think that job’s taken for a while - mind you, I said that about Doctor Who," he said.

Even if he doesn’t get his wish, David has apparently been inundated with offers of work as a result of his star turn as the Doctor.

He is now gearing up to play a driving instructor in a new BBC film. Learners starts shooting this month and will be shown later this year.

David swaps Tardis for L plates - April 4 2007
Doctor Who star David Tennant is to play a driving instructor in a new BBC film.

The BBC One comedy drama about a group of learner drivers was written by Spaced actress Jessica Stevenson.

She also appears as Bev, a downtrodden wife who has failed her driving test eight times.

She develops a crush on her new instructor, played by David, a devout Christian who is secretly in love with the glamorous driving school owner.

The film, Learners, starts shooting this month and will be shown later this year.

Jessica said the film was based on her own experiences as a hopeless driver.

"It took me 10 years to pass my test - this year I finally did it so I could do the film," she said. "I had a great instructor who taught me to take my time and relax. When I passed I cried with joy."

David is currently starring as the Timelord in the third Russell T Davies series of Doctor Who.

The show will be back for series four - but Tennant has refused to reveal whether he will return in the lead role.

Doctor Who to light up Blackpool - April 1 2007
David Tennant is set to light up Blackpool this summer when he switches on the world-famous illuminations.

The Doctor Who hunk will be swapping the control panel of the Tardis for the controls of the six-mile long glittering light display during a free concert in August.

Jackie Potter, Strategic Director of Tourism and Regeneration, said: "We are absolutely delighted that David Tennant has accepted our invitation. The Switch On celebrations are enjoyed by a huge family audience and we are sure this will be a popular choice."

David, who returns to our screens tomorrow in the new series of Doctor Who, will be guest of honour at the brightest night in Blackpool’s year.

Jackie added: "The concert during which he will throw the switch marks the start of Blackpool’s Big Switch On Weekend. We hope that thousands of fans of David, and of Blackpool, will join us in the celebrations."

Illuminations bosses are also set to unveil plans for a new display featuring characters and creatures from forthcoming episodes of Doctor Who.

David is the latest in a long list of stars to have launched the lights, including the fourth Doctor, Tom Baker, who illuminated the town back in 1975.

Blackpool Illuminations shine along six miles of the promenade for 66 nights from August 31, 2020 until November 3, 2007.
