Light the torches! 'Survivor' reboots

As it enters its 24th round, are there any fresh twists left for "Survivor"?

Luckily for multiple-Emmy-winning host and producer Jeff Probst, there are.

Eighteen new players tackle the show's credo by trying to "outwit, outplay (and) outlast" their rivals as CBS launches "Survivor: One World" Wednesday, Feb. 15. The contestants, divided by gender, have to share a beach and withstand all the elements Mother Nature throws at them ... while developing strategies that may involve the opposing team, given the surprising alliances that can be formed.

"We had talked about this idea of 'One World' for a while, and what would happen to the dynamics if we just left (the competitors) out there to live together with no rules. They could build one camp or two, or four. They could cross-pollinate as much as they wanted, but when it came time for the challenges, they would have to be two tribes."

And the changes didn't stop there, Probst notes: "Then we decided to add another layer and do men vs, women, because of the differences in how the sexes behave ... and also the component of men wanting to show off for women, and women using their charm to get to do things. We thought that would really mix it up."

Probst, who also starts a syndicated talk show this fall, says "Survivor: One World" includes "some big characters. We have a guy whose real name is Greg Smith, but the 'name' he gives himself is Tarzan. And he doesn't look like Tarzan. He's a 64-year-old plastic surgeon, and he's an opinionated know-it-all who actually does know a lot, so you can't always argue with him. He can back it up."

On the female side, Probst points to Kim Spradlin, a bridal shop owner who's recently divorced. "She's very likable and has great energy, and she came into this just because she needed a new thing, an adventure. When you get someone in that state of mind, you're getting someone who comes in very differently than a superfan who's always wanted to play. She's got another layer, and that can work for you. But it can also work against you."
