Clip: Ryan Reynolds stars in Turbo (Exclusive)

New footage from DreamWorks 'toon about a snail who dreams about becoming a racing driver.

Ryan Reynolds lends his vocal talents to DreamWorks' latest animation 'Turbo'.

The star plays Theo, a.k.a Turbo, a common garden snail who dreams of being the greatest racer in the world. Amazingly, a freak accident might help him become just that, but before that it's just a pipe dream, as you can see from our exclusive clip.

Samuel L. Jackson, Paul Giamatti, Bill Hader and snoop Dogg (obviously) co-star.

'Turbo' is released in the UK on 18 October.
