Trivia: In one scene Daffy suggests the team name the Ducks. Bugs then responds, "What kind of Mickey Mouse organization names a team the ducks." This refers to the 1992 Disney film "The Mighty Ducks."
Trivia: When the aliens first go to steal the talent of the NBA players, there are two fans in the stands with about a minute of screen time - the first is Patricia Heaton from "Everybody Loves Raymond", and the second is Dan Castellaneta - the voice of Homer Simpson.
Trivia: Larry Johnson said that his grandmother plays better than him. He actually starred in a commercial, as well as an episode of Family Matters, playing basketball as his grandmother.
Trivia: The gym where the Looney Tunes characters practice is called the "Schlesinger Gym" - a reference to Leon Schlesinger, who was the first producer of the Warner Brothers cartoons.
Trivia: After the Monstars steal the talents of five NBA players, the NBA suspends its season fearing an unknown contagion could be affecting its players. This ended up becoming a reality for the NBA in March 2020, as the NBA indefinitely suspended its season following the discovery that Utah Jazz All-Star Rudy Gobert (and later his teammate Donovan Mitchell) tested positive for COVID-19.
Trivia: The end of the film shows Jordan's motivation to return to the NBA is when his ability to play is questioned by the other players in the film. This isn't far off from reality. In real life, part of what fuelled his return to the NBA was when he was visiting Utah Jazz members and former Dream Team teammates Karl Malone and John Stockton while the Jazz were in Chicago, and young Jazz guard Bryon Russell approached Jordan and asked him why he retired, and told him he could guard him. Coincidentally, Russell would end up trying to guard Jordan on his final possession as a member of the Bulls, which saw Jordan sinking the game winner of the 1998 NBA Finals.
Suggested correction: Both of these people were also credited in the film for their appearance, so this wouldn't be trivia.
