The lady who taught Billy Elliot to dance dons the mantle of mentor once again in Driving Lessons. Well-loved British actress Julie Walters teams up with her Harry Potter co-star Rupert Grint as a deliciously dotty retired actress who inspires Grint's timid teen to hit the road and take control of his own life.

WATCH: The stars of Driving Lessons on bad language, bad poetry and controlling that clutch.

Driving Lessons is released in UK cinemas on Friday 8th September 2006.
