Normally, you find out the voice behind your favorite cartoon characters and think 'wow, that's nothing like what I imagined!' But, looking at Meg Ryan, she probably could play Dr. Blight in a live action version of Captain Planet and The Planeteers. All she would have to do is dye that front strand of hair white and she'd be ready to go.
Ryan started work on Captain Planet and The Planeteers after starring in major Hollywood classic, When Harry Met Sally. For someone with such a famously sweet personality, it was an interesting role for her, playing a villain. But she helped educate kids of the '90s about environmental issues, so maybe she was still being sweet after all. Ryan obviously went on to become one of Hollywood's most loved actresses - good on her, we say!
