Sir Billi is a 2012 British animated comedy adventure film directed by Sascha Hartmann and written by his wife Tessa Hartmann, based on an original story they developed together. Produced by Billi Productions, the film stars the voices of Sean Connery, Alan Cumming, Patrick Doyle, and Kieron Elliott. Set in the Scottish Highlands, the film follows Sir Billi, an elderly veterinarian who, with the help from his friend Gordon the Goat and the townspeople of Catterness, embarks on an adventure to rescue a beaver named Bessie Boo, while also helping her escape from a corrupt police officer. The film is Scotland's first computer-animated feature film. Connery had actually retired in 2006, but eventually joined the film's cast as a favour to the Hartmanns.
