Space Jam: A New Legacy Trailer Released A New Legacy. LeBron James will lead the Tune Squad onto the hardwood this summer. He’ll be joined by Bugs Bunny, Daffy Duck, Lola Bunny, and all the classics. Along for the ride this time is Don Cheadle who plays Al G Rhythm, an AI looking for a way to siphon followers off of the NBA superstar. The entire conceit gets even stranger as LeBron and pals will have to visit movie universes from the entire Warner Bros. catalog. Casablanca and Joker were mentioned by name in some recent interviews, so the sky is clearly the limit when it comes to this new movie. CGI has come a long way when dealing with animated characters. The fur textures on Bugs and some of the visual effects look like they will be a big hit with younger audiences. Check out the trailer here for yourselves.
