20/20 10 p.m., Channel 5

Cher (above) has been promoting her new movie, “Burlesque,’’ like crazy. She looks exactly the same in all the magazine photos, too, smiling — but always with her mouth closed. What’s up with that? Anyhow, tonight she talks to Cynthia McFadden about dating, money, her Las Vegas show, and, of course, her feelings about Chaz.

The Walking Dead 10 p.m., AMC

AMC is re-airing each Sunday episode of “The Walking Dead’’ on Fridays at 10. In tonight’s episode, you can really see how the horror-movie premise will work as a series. There’s a lot of relationship drama at the camp outside Atlanta, as the survivors are thrown together despite their serious differences in personality and background. It’s “Lost’’-like, and the group will undoubtedly come across their own version of the Others. By the way, this season is only six episodes long, but AMC has already announced a second, 13-episode season due next year.

Dangerous Encounters 9 p.m., National Geographic

Electric eels. I prefer acoustic.

Storm Chasers 10 p.m., Discovery Channel

Also known as drama queens.

Homemade Millionaire 10 p.m., TLC

Inventing, not counterfeiting.
