Continuity mistake: As paramedics inflate Jordan's assistant Stan Podolak following his lone bucket, the scoreboard shows the Monstars ahead 77-67 with 10 seconds remaining. Yet following his treatment and the surprise entrance of Bill Murray, the score has changed to 77-76 with no time having elapsed.THGhost
Character mistake: When Stan inflates himself, Michael asks, "How'd he do that?", implying that he doesn't know the rules of the Looney Tunes world. Since Michael was rolled into a ball by the aliens earlier in the film, this shouldn't be too much of a surprise.
Continuity mistake: When Stan's body has been "deflated", his body is laying over the 3-point line. Then when the doctors rush over to him, he is laying a good distance away from the 3-point line. When the air pump is stuck in his mouth in the very next shot, he is laying over the 3-point line again.
Continuity mistake: When the alien boss is watching Looney Toon cartoons in the beginning, the cartoons change between shots of him saying "Looney. That's the word I was looking for" even though they are not changing in earlier shots.
Continuity mistake: After the Looney tunes challenge the aliens to a basketball game, the aliens change position when they all yell "All right, basketball.".
Continuity mistake: After Wile E. Coyote crashes into the auditorium, Daffy steps on his nose. On the very next shot, Daffy is walking in the aisle, but Wile E. is not visible behind him.
