The Doctor to take on learner drivers

Doctor Who star David Tennant is to play a driving instructor in a new BBC film.

Learners, the BBC One comedy drama about a group of learner drivers, starts shooting this month and will be shown later this year.

It was written by Spaced actress Jessica Stevenson, who also appears as Bev, a downtrodden wife who has failed her driving test eight times.

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

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 series of Doctor Who, written by Russell T Davies.

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