Fat Albert is a 2004 live-action/animated fantasy romantic comedy film based on the Filmation animated series Fat Albert and the Cosby Kids. The film was produced by Davis Entertainment for 20th Century Fox, and stars Kenan Thompson as the title character.
The plot surrounds Fat Albert and the gang leaving the 1970s cartoon world and entering the 21st century real world in order to help a teenage girl, Doris Robertson (Kyla Pratt), deal with the challenges of being unpopular, and not having any friends except her foster sister. Doris withdrew after the death of her grandfather, Albert Robertson, who was the real-life inspiration for the Fat Albert character. Fat Albert and the gang must show her that she is special and that she can make friends. But if Albert and his friends stay in the real world, they will turn to celluloid dust, and it is up to Bill Cosby to help them get them back into the cartoon world.
Unlike films that meld the cartoon world with the real world while at the same time keeping the cartoon characters two-dimensional (e.g., Who Framed Roger Rabbit, Space Jam, Looney Tunes: Back in Action), Fat Albert takes a twist and transforms the cartoon characters into three-dimensional humans, who have to come to grips with the differences that exist between their world and the real world.
