Jane Fonda and Lily Tomlin Say They'd Cast Britney Spears in 'Nine to Five' Today

The 'Grace and Frankie' actresses also dish on the advice they'd give their younger selves.

Jane Fonda
and Lily Tomlin first had us cracking up on the big screen in Nine to Five. 35 years later, the acting legends are back together in the new Netflix comedy series Grace and Frankie.

ET caught up with the long-time friends who shared their thoughts on whether now is as good a time as any for a remake of the 1980 comedy.

"We'd have to be on the fringes," Tomlin said. "They'd probably cast Britney Spears."

Fonda, who was one of the film's original producers, admitted that 20th Century Fox owns the right to Nine to Five and that the studio hasn't been interested in a remake. So the likelihood of seeing it back on the silver screen (with or without Brit Brit) is slim to none. Luckily for fans they'll have 13 glorious episodes of the Netflix comedy to get their Fonda/Tomlin fix.

In the series, which drops May 8, Fonda (Grace) and Tomlin (Frankie) are a pair of rivals forced to lean on each other for support when they learn their husbands have fallen in love with each other and want to get married. The actresses told ET it wasn't a hard-sell for them to join the project.

"Television is where a lot of the best writing is now," Fonda said. "You can be edgier and so it's just very attractive. Especially for older people."

Fonda, 77, and Tomlin, 75, are as sharp and funny as ever, proving that some things just get better with age.

"We want to address the stereotype, which is that after a certain age it's all down hill and there's no more joy or sex or play," Fonda explained. "It's simply not true."

As for the advice they'd give their younger selves? "Wear suncreen," Tomlin joked. "Save a portion of your income every week, no matter what you have to give up. Even if it's sunscreen."

"When I was young I never thought I was going to make it past 30," Fonda added. "I thought I was going to die of alcoholism and loneliness and you know that hasn't been the case... Don't give up no matter how hard it is. Try to make the best of who you are."
