I think we took a wrong turn at Albuquerque...
- The Warner Bros. water tower falling down and flooding the studio is arguably the most dramatic and realistic scene in the whole movie. Even Bugs is visibly shocked for a moment as the tower falls.
- Shaggy Rogers threatening and Scooby-Doo viciously bearing his fangs and growling at Matthew Lillard can be a bit disconcerting due to being totally out of character.
- DJ Drake's father's message telling him to help him out while he's being interrogated. Somewhat Nightmare Retardant later when we see a scene where DJ's dad beats up the more bumbling henchmen of Mr. Chairman.
- The aliens in Area 52 that Marvin the Martian sets free to attack, DJ, Kate, Bugs Bunny and Daffy Duck to get the playing card. Especially since the CGI on some of them hasn't aged very well.
- During the Louvre chase scene, one of the paintings they enter is Edvard Munch's "The Scream" where Daffy and Bugs run into the figure in the painting and he screams at them, pictured above. Elmer then catches up and Bugs stamps on his foot, causing him to make the same nightmarish face as the figure. The way the figure wails coupled with Elmer's depiction of the painting, makes for a very unnerving part of the film.
- In the same scene, going through Salvador Dalí 's The Persistence of Memory. Much like the clocks and other objects in the painting, Bugs, Daffy and Elmer start melting as they run through... It's pretty jarring to watch.
- The introduction to Taz where he eats up the skin of one of Mr. Chairman's henchmen after calling him "stupid". Its Played for Laughs but since it happens to a live action person rather than a cartoon character it can scare some kids (and adults). Mitigated by the henchman cartoonishly withdrawing his objection as a skeleton.
