Garfield
From Tardis Wiki, the free Doctor Who reference
Garfield was a comic strip.
In 1981, Peri Brown read the Garfield cartoons which were posted on Bob Salmon's door. (PROSE: Blue Box)
In 1997, Sarah Jane Smith looked for a magazine which had a Garfield strip while waiting in Pimms Shipping's reception area. (PROSE: Bullet Time)
Behind the scenes
Two live-action and CGI hybrid films based on the strips were released in 2004 and 2006. The second of these films, which saw the character travel to the UK, featured Richard E Grant amoung the voice cast, while Lucy Davis and Jane Carr appeared in live-action roles.
