Fat Albert is a 2004 live-action/animated film based on the Filmation animated series Fat Albert and the Cosby Kids. The movie 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 cartoon world and entering the real world in order to help a teenage adolescent deal with the challenges of being unpopular, and not having any friends except her adopted sister. Her unpopularity stemmed from her tendency to withdraw into a world of her own as a consequence of the death of her grandfather, Albert Robertson, who was actually the inspiration for the Fat Albert character. It is up to Fat Albert and the gang to show her that she is special and can make friends.
Unlike some movies that melt the cartoon world with the real world while at the same time keeping the cartoon characters two dimensional, e.g. Who Framed Roger Rabbit, 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 (like Enchanted).
Fat Albert also notices Lauri and falls in love with her. In another attempt to help Doris, the gang persuades some cheerleaders to invite them all to an outdoors party. With some reluctance, Doris agrees to attend. While they're there, Lauri dances with Fat Albert. Lauri's annoying ex-boyfriend Reggie (Omarion) attempts to make her jealous by dancing with Doris. When Lauri doesn't notice him, he tries to kiss Doris. Doris runs from the party and Fat Albert warns the boy to stay away from Doris. The next day, Doris goes to school, but asks the gang to go to the park instead of following her. Weird Harold, normally very clumsy, joins in a basketball game and is able to play perfectly. Mushmouth, who can't talk normally, is taught how to speak by a little girl. Dumb Donald goes to the library and is able to read and remove his purple face-covering hat.
When Doris gets them and takes them back to her TV, Bucky, Dumb Donald, and Weird Harold jump into the TV but the show ends before the others can enter. Fat Albert and Bill have an argument in private about going back (Fat Albert wants to stay in the real world with Lauri). Searching for guidance, Fat Albert meets the real Bill Cosby and tells him of the dilemma. Cosby tells him that his character is based on Doris's grandfather, which explains Doris's confusion over why Albert seems so familiar to her. Cosby then tells Fat Albert that he has to return to the TV, or he will turn into celluloid dust. Devastated, Fat Albert tries to tell Lauri that he has to leave, but she doesn't believe he's from the TV and thinks that he is just being insensitive.
The next day, Bill, Mushmouth, and Rudy jump back into the TV. Fat Albert waits and goes to a track meet that Doris and Lauri have, then takes them home and jumps into the TV (this convinces Lauri that Fat Albert wasn't lying to her). At the end of the movie, Bill Cosby and his old friends (who the characters in the show were based on) stand in front of their old friend Albert Robertson's grave. Doris is also there. Then the group of men have a little race, showing no matter how old they are, they are still kids at heart, the same kids from the TV show that they helped Bill Cosby inspire.
