Although he originally focused on illustration, Sadler later turned his hand to stop motion animation. He graduated in 1993. He began his professional career as a freelance model/set builder before returning to animation. During the 1990s he worked for various film production companies including Bolex Brothers and Elm Road Studios in Bristol, Aaagh Animations in Cardiff and Gnome Productions in Wellington, New Zealand.[citation needed]
He first worked for Aardman Animations in 1994 as a freelance animator and model maker, working on several commercials and the pilot episode for Richard Goleszowski's Rex the Runt series. This led to him being given his first chance to direct when the second series went into production in 2001. In 1999 he was a member of the animation team on Robbie the Reindeer for the BBC, his last independent production before joining Aardman.[citation needed]
He became a full-time Aardman staff member in November 2000 and enjoyed several roles during his time there, including key/character animator on the stop frame feature film projects, "Chicken Run", "Curse of the WereRabbit" and "The Pirates! In an adventure with Scientists!" He joined the Shaun the Sheep team in late 2005, helping to develop the look and animation style of the series and was director of ten episodes.[2]
He was made series director for the second series of forty episodes, which completed production in March 2010. After the filming of "The Pirates! In an adventure with Scientists!" completed in December 2011, he returned to direct five more episodes of "Shaun the Sheep" series 3. He left Aardman Animations in August 2012.[3]
