Earth! Fire! Wind! Water! Heart! By your powers combined, I am . . . Captain Planet!
The show, a brainchild of Ted Turner, came before its time. The series ran from 1990 to 1992, just as environmentalism was beginning to enter the mainstream consciousness. And while its take on environmentalism was a little strange ("Heart?"), it helped catalyze a generation's passion for protecting the earth. It made green activism cool, and the nonprofit that came after it continues to do good work today. Now that green thinking is so much more widespread, we hope the film version will be a huge hit.
