A concept piece for one of the many scrapped sequel ideas. This one is Skate Jam featuring Tony Hawk from 2001.
- A Space Jam sequel was planned as early as 1996, shortly after the original film was theatrically released worldwide. Titled Space Jam 2 and directed again by Joe Pytka, the sequel would have involved Michael Jordan teaming up with the Looney Tunes again for a new basketball competition against the alien Berserk-O!, who was going to be voiced by Mel Brooks, and his henchmen. However, the sequel was cancelled when Warner Bros. found out that Jordan hadn't signed a contract for a sequel and a producer had lied to keep development going.
- Other sequel ideas for a second Jam film with a celebrity protagonist involved Spy Jam starring Jackie Chan (which likely evolved into Looney Tunes: Back in Action starring Brendan Fraser), Race Jam starring Jeff Gordon (who cameoed on Back in Action) and Skate Jam starring Tony Hawk (this last one was cancelled after Back in Action underperformed). Joe Pytka was also pitched to do a spin-off starring Tiger Woods (perhaps Golf Jam) which would have brought Jordan back in a small role.
- Retired basketball player Kobe Bryant showed an interest in directing the film. He was uninterested in doing a cameo if asked as he didn't really like acting and wanted to pursue a filmmaking career, having already written and narrated the short film Dear Basketball. However, Terence Nance had already been hired by that point.
- Kath Soucie was originally announced to be reprising her role as Lola Bunny from the original film. However, when the first trailer was released, it was revealed that Zendaya would be voicing Lola instead. It's unknown whether Soucie was recast, the reports were wrong and assumed Soucie's return (said reports also claimed Bugs would be voiced by Eric Bauza; in the film the character is voiced by Jeff Bergman) or if Warner replaced her with Zendaya at the last minute.
- Pepé Le Pew was supposed to have a role where his Casanova Wannabe tendencies would land him with a restraining order against any toons, and that he wasn't allowed to touch anyone ever again. However, the character wound up being removed from the film, as well as certain future projects in the franchise. Supposedly, it was partially finished for test screenings before it wound up being cut.
- On the topic of Pepé Le Pew, Penelope Pussycat was planned to be part of TuneSquad for the sequel. She was even included in early promotional material (such as the December 2020 reveal
) complete with official artwork and merchandise of Penelope wearing the film's new TuneSquad outfits. By the time the official teaser dropped on March 2021, she wasn't featured in any footage or the movie itself, although she appears in three panels of the Comic-Book Adaptation. - Quad City DJ's, who recorded the original film's famous theme song, had recorded a brand new theme for the soundtrack, and even released a teaser, but it didn't make in onto the soundtrack or film.
- An alternate version of the Fourth Wall Psych gag.
- Instead of LeBron and Bugs finding Daffy and Porky in the DC Animated Universe, the two would have been in the world of Pokémon: The Series note , where Daffy was using Porky (or rather Porkachu) to fight in Pokémon battles for cash. A scene was storyboarded out where Daffy was using Porky to battle Brock, and there was going to be an Ascended Meme with the "Surprised Pikachu" making an appearance. Both Nintendo and The Pokémon Company loved the scene and were eager for it to appear in the movie. However, as the story progressed, the scene wound up being changed to feature the DCAU instead.
