Wallace And Gromit creators Aardman Animations are leading this year's (08) British Animation Awards with a total of four nominations. The U.K. production company has picked up nods in categories including Best Short Film for The Pearce Sisters and Best Children' Series for Shaun The Sheep: Still Life. Tim Burton's murder musical Sweeney Todd: The Demon Barber Of Fleet Street has also been nominated for Best Film and TV Graphics at the annual awards. The Oscar-nominated film starring Johnny Depp was rated for its opening titles, which feature a cartoon sequence of the grisly tale's plot. Director Burton previously picked up the honour for animated movie The Corpse Bride in 2006. The winners will be announced on 13 March (08) in a ceremony at London's National Film Theatre.
