Pixar's new 'Toy Story' short 'Partysaurus Rex' - video
The six-minute film centres on Rex the Dinosaur (voiced by Wallace Shawn) as he gets left behind in the bathroom and kick-starts a party in the bathtub.
Partysaurus Rex is the third Toy Story short following on from Hawaiian Vacation, which played in front of Cars 2, and The Muppets opener Small Fry.
The latest film has already screened before Finding Nemo 3D in the US. The Pixar classic will return to UK cinemas next March.
A sequel to Finding Nemo is currently in the works with original director Andrew Stanton at the helm.
