Star Senior Citizens Are Doing … What?

Maybe McMahon's not on the level of Snoop or Dre. But his venture propelled him back into the headlines for all the right reasons, which was the goal. It's been a common theme this year: For many older stars, post-50 power plays have paid off.

"Some of these over-50 celebs are doing their best work in these years. Look at Clint Eastwood. Dustin Hoffman has a great movie coming out. Glenn Close just won an Emmy," said Meg Grant, entertainment editor for AARP the magazine. "We've seen, in this past year, a difference in the physicality: Harrison Ford still doing 'Indiana Jones' and still using his body, Meryl Streep dancing and singing in 'Mamma Mia.' That scene where she pulls Pierce Brosnan's shirt off? You normally see actors in their 20s doing that."

Leachman -- and the, ahem, assets of hers that caused "Dancing With the Stars" judge Len Goodman to shout "Mind your cleavage!" last week -- fits firmly in that category.

The 82-year-old Academy Award-winning actress took over the dance floor Sept. 22 during the Season 7 premiere of "DWS." She begged viewers to vote for her because she was an orphan, thrust her gams up on the judges' table and hopped on top of judge Carrie Ann Inaba's lap. She may not last long on a show that's put her toe-to-toe with the likes of Brooke Burke and Kim Kardashian. But she sure as hell isn't going down without a fight.

Then there's Shatner. The 77-year-old "Star Trek" vet and "Boston Legal" HR-violation-waiting-to-happen took to YouTube to clear up any confusion about whether or not he'd reprise his role as Captain Kirk in J.J. Abrams' "Trek" movie. Earlier this month, Abrams told SciFi Scanner he came up with a way to bring Shatner back as Kirk but nixed the scene because "it didn't quite feel right."

In a YouTube video posted last week, Shatner said he was never told about the possible role.

"Nobody ever came to me and said, 'We have a cameo,'" he says. "The truth is, I wouldn't have wanted to do a cameo because you were having trouble fitting it in. … I'm just sorry that I'm not in your wonderful movie. I would've loved to have been in it. If you make another one, maybe you could think of ways of bringing Captain Kirk back to life."
