D.J: What I really do is I... I'm a stunt boy! Daffy: HA! You, a stunt boy!? Please! D.J.: I am! You seen those Mummy movies? I'm in them more than Brendan Fraser is! (A lot of Fraser's commentary for the first Mummy movie is him pointing out stunts he didn't do.)
Taken to extremes when D.J confronts 'Brendan Fraser' and punches him out for getting him fired.
Creator Backlash: Since the film came out, Joe Dante has really only discussed this movie publicly just once. The one time he did all he could talk about was the Executive Meddling behind it, and "the less said about [the movie], the better." He did say though that "At least it's better than Space Jam".
Creator Killer: Warner Bros. Feature Animation, which had yet to produce a single financially successful film since 1998 (mostly due to poor advertising and the studio only having a passive interest in animated features) finally collapsed after this film failed.
Franchise Killer: The faltering merger of Time Warner and AOL caused all official merchandise to end years earlier. But this film! This film put an end to any major Looney Tunes production for good... and only until five years later would someone revive them into a television show!
Not only this, but one year after the film's release, the classic Looney Tunes shorts were canceled from Cartoon Network, and were not seen on TV for nearly half a decade until Cartoon Network slowly began to bring them back in 2009.
Instead of Brendan Fraser, Jackie Chan would have been the star.
According to the deleted scenes, the movie was originally to have a completely different opening and ending plot progression, the opening being a Batman parody while the plot itself would have stayed in the jungle and involved Tweety (who was apparently supposed to stick around with the heroes) to a greater extent.
