While both films feature the Looney Tunes characters, they are separate stories with different plots and casts.
* Space Jam (1996) features Michael Jordan playing basketball against the Monstars, who have stolen the talents of NBA players.
* Looney Tunes: Back in Action (2003) follows Bugs Bunny and Daffy Duck on a globe-trotting adventure to save the Warner Bros. studio from a villainous director.
Although there are some visual similarities, Looney Tunes: Back in Action is a completely independent film and not a continuation of the story from Space Jam.
