Context paragraphs:
Fat Albert (film): Fat Albert is a 2004 American live-action/animated fantasy romantic comedy film based on the Filmation animated series of the same name created by Bill Cosby.  The film was produced by Davis Entertainment for 20th Century Fox, and stars Kenan Thompson as the title character alongside Cosby himself in a key supporting role.  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", ""), "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.  The film acts as a continuation of the series; its plot surrounds Fat Albert and the gang leaving their 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 aside from her foster sister, Lauri.  Doris has withdrawn and fallen into depression after the death of her grandfather, Albert Robertson (who was a friend of Cosby and the real-life inspiration for the Fat Albert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 Fat Albert and his friends stay in the real world, they will turn to celluloid dust, and it is up to Cosby to help them get them back into the cartoon world.
