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.

Who is the coolest man on TV? - Mar 28 2007
David Tennant’s incarnation as Doctor Who has been voted the coolest TV character.

The time-travelling doctor beat federal agent Jack Bauer, played in the hit US show 24 by Kiefer Sutherland, to second place.

Christopher Eccleston, 43, the actor David, 35, replaced as the Doctor on the BBC sci-fi show, did not make the top 10. The poll for radiotimes.com was conducted to find the coolest character - defined as laidback and sexy - on TV.

The Fonz in the Seventies TV show Happy Days, played by Henry Winkler, now 61, came third.

Colin Firth’s heart-fluttering turn as Mr Darcy in the TV adaptation of Jane Austen favourite Pride And Prejudice is fourth, followed by The Cat in Eighties comedy series Red Dwarf, brought to life by Danny John-Jules.

No women made it into the top 10 list, voted for by more than 4,000 TV fans.

Sixth place went to chauvinist DCI Gene Hunt in Life On Mars, played by Philip Glenister, while his politically correct fellow cop Sam Tyler does not get a look-in.

Big Brother’s Little Brother host Dermot O’Leary, in seventh position, was the only non-fictional character to make it into the top 10, while The Magic Roundabout’s rabbit Dylan (ninth) is the sole animated character.

Others in the top 10 include Columbo (Peter Falk) and Sawyer in Lost (Josh Holloway).
