"I have a sort of a vision of what it could be and that's all that I'll say," Fonda said in an interview last week. "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."
Fonda says she's also writing a book about aging called "Prime Time: Creating a Great Third Act." It is due out next year.
"It was the research that I did while writing my book on the aging body that motivated me to get back into the fitness industry again," Fonda said, who hasn't released a workout video since 1995.
She recently finished filming two movies and will take her Tony-nominated performance in the Broadway play "33 Variations" to a Los Angeles theater next year. Fonda said as she gets older, life gets easier.
"You get a little wiser as you get older. You've been there, done that. You know it's not gonna kill you. You've survived it before. You tend to make lemonade out of lemons instead of mountains out of mole hills," she said.
