"I think the best, edgiest writing is now on cable television. It's pretty exciting." While the Oscar-winner hasn't officially signed up for a TV show, she can be seen in new workout DVDs designed specifically for baby boomers.

"People who are of a certain age tend to be ignored by the fitness industry and being that I'm older and I've done a lot of research on what happens to a body when it gets older, I know that it's essential that we stay active," Fonda said. The 72-year-old recently released "Jane Fonda: Prime Time Walkout" and "Jane Fonda: Prime Time Fit & Strong."

She says too many older people dismiss working out, and that needs to change. "It's the worst thing that a person could do when they're older is to say, 'Why bother now? I'm older. I don't need to,'" Fonda said.

"I'm on this crusade to get older people out of the chairs, off their couches, moving in a way that's safe, easy and very doable even if they've never done it a day in their lives. It's never too late."
