10 Worst Practical Effects In Movie History

10. Terrible Live Action & Animation Hybrid - Cool World

There are many, many reasons why Who Framed Roger Rabbit looks as good as it does, but it all boils down to a lot of things going right exactly when they needed to. If the stars hadn't aligned for Roger Rabbit the way that they did (one of them being Bob Hoskins), we'd have gotten, well, something like Cool World.

Cool World goes for the same kind of animation and live-action hybrid Roger Rabbit does but without the same careful attention to detail. No bumping the lamp in this movie, instead, the audience is riddled with constant reminders that Brad Pitt is not looking at a real person.

When Roger Rabbit walks across a room, you can see his feet touching the ground as he moves. Every little detail in the geography of the scene has an impact on how he looks and behaves. Meanwhile, Holli Would looks like she's constantly hovering just above the ground. There's no dynamic between the animated characters and the live-action environments and people.

Cool World is what would've happened if Roger Rabbit didn't have the budget and ingenuity that it did, and was the fitting final nail in the coffin of Ralph Bakshi's time in Hollywood.
