Meg Ryan, Sting, Jeff Goldblum and More Surprise Celebs Who Voiced Captain Planet’s Bad Guys

Take a look back at the '90s cartoon's villains — and the big stars who played them

In 1990, a brand new superhero emerged to save the earth, not by punching out costumed criminals, but by raising awareness of environmental issues.

Captain Planet was the brainchild of media mogul Ted Turner, who specifically wanted to create a cartoon that would teach kids about the dangers of pollution and overconsumption while empowering them to take action themselves. The show was a hit, and if you grew up in the ’90s, you can probably remember its theme song without even trying too hard!

But what you may not remember is that the show featured an impressive roster of celebrities lending their vocal talents to bring Captain Planet’s rogue gallery of polluters and profiteers to life — along with a few of his allies.

Here, take a look back at all the A-listers who voiced Captain Planet characters.

Tom Cruise as Captain Planet

It may come as a surprise to many fans, but Tom Cruise was initially cast as the voice of Captain Planet’s titular hero. As Marsha Goodman, the show’s original voice director, told Slate’s Decoder Ring podcast recently, the Mission Impossible star himself reached out to her office wanting to voice the role. Ultimately, however, Cruise had to bow out after recording several episodes, and his vocals were rerecorded by David Coburn.
