[citation needed] The pair are credited for 'additional dialogue' for the Aardman film Chicken Run, but after a decade of collaboration, Burton and O'Farrell began to work on separate projects.

Although he continued to do some TV comedy scriptwriting (with credits for 2DTV, Never Mind the Buzzcocks and Mike Bassett: Manager) Burton began to focus on screenwriting, most notably with the DreamWorks Animation Madagascar.

Other major screenplay credits include Wallace & Gromit: The Curse of the Were-Rabbit (which won an Oscar in 2006 for Best Animated Feature Film), Gnomeo and Juliet and Aliens in the Attic.

He also wrote and made his directorial debut with Richard Starzak with Shaun the Sheep Movie, which got nominated for the Academy Award for Best Animated Feature.
