Saturday TV: Boxing Brothers, Other Bouts

I don’t keep up with this stuff very well, but apparently the reigning heavyweight boxing champions are a pair of brothers.

“Klitschko” (HBO, 5:30 p.m.) chronicles the tale of Wladimir and Vitali Klitschko, who grew up quite tall in the Ukraine. They may be familiar to viewers – together they’ve won 24 bouts on HBO already, but they vow never to box each other.

Their story begins in the Cold War upbringing, a father who worked cleanup at Chernobyl, and follows their rise in boxing across different cultures, at the Olympics and professionally.

The fascinating tale is told by Sebastian Dehnhardt and kicks off a night that also includes a triple header of World Championship Boxing (HBO, 9:45 p.m.) that will include Vitaili Kiltschko vs. Manuel Charr from Moscow.

There is some other premium cable boxing (Showtime, 9 p.m.) with Randall Bailey vs. Devon Alexander

It’s practically all sports in prime time with Nebraska at UCLA (Fox, 7:30 p.m.) in college football, a Sprint Cup NASCAR Race (ABC, 7:30 p.m.) from Richmond, and the woman’s final in the U.S. Open (CBS, 8 p.m.).

Susan Lucci hosts the saucy true crime re-enactment series “Deadly Affairs” (Investigation Discovery, 10 p.m.). Like many of the series on I.D., there is a certain unseemly lightness to the proceedings, which I asked them about at the TV Critics press tour last month and wrote about here.

“Doctor Who” (BBC America, 9 p.m.) set a record for the network in its return last week. Tonight’s new episode might do even better, as it is titled “Dinosaurs on a Spaceship.”

Sometimes it’s so obvious what’s going to happen in the very first seconds of  a Hallmark, the only satisfaction comes in finding you were write. In “Puppy Love” (Hallmark, 9 p.m.) a minor league ballplayer loses his shaggy dog, the pound picks it up and it’s adopted by an attractive single mother. You guess what happens next. Candace Cameron Bure and Victor Webster star.

The canine in the movie, Jake, could frankly use some training from the “Dog Whisperer” (Nat Geo Wild, 8 p.m.), who in the second to last episode, tires to help Jillian Michaels’ Chihuahua and Kelsy Grammer’s dogs Elvis and George have housebreaking problems.

Among other animals, “My Cat from Hell” (Animal Planet, 8 p.m.) has a season finale.

The Channing Tatum romance ,“The Vow” (Starz, 8 p.m.) only came out in theaters earlier this year, but already it’s making its premium cable debut. Also on tonight, “Extremely Loud & Incredibly Close” (HBO, 7:30 p.m.) and “The Hangover Part II” (Cinemax, 10 p.m.).

Abby and Brittany have nothing to do with “2-Headed Shark Attack” (Syfy, 9 p.m.). From a network that specializes in ridiculous shark movies, such as “Sand Sharks” (Syfy, 7 p.m.).

It’s that time of year again for memorial documentaries. A new one this year is “9/11 Emergency Room” (TLC, 8 p.m.), folloed by “9/11: Heroes of the 88^th Floor” (TLC, 9 p.m.).

Wedding season may be over but “My Fair Wedding with David Tutera: Unveiled” (WE, 9 p.m.) begins its sixth season with a burlesque-themed ceremony. Throw out the garter and the whole thing’s over.

Whatever happened to Jay Mohr? He’s doing standup specials, such as the new “Funny for a Girl” (Showtime, 8 p.m.).

Tess Akins stars as a daughter who struggles to find out who murdered her mother in “A Killer Among Us” (Lifetime, 8 p.m.).

Jack Osbourne may rightfully have nightmares growing up in a household where his dad would bite off the heads of bats. So sure enough he’s on “Celebrity Ghost Stories” (Bio, 9 p.m.) tonight.

Precocious girls is the theme on Turner Classic movies with “The Goodbye Girl” (8 p.m.), “The Bachelor and the Bobby-Soxer” (10 p.m.), “Andy Hardy’s Blonde Trouble” (11:45 p.m.), “Lost Angel” (1:45 a.m.) and “Little Women” (3:45 a.m.).

Pearl Jam plays a replay of “Austin City Limits” (PBS, 9 p.m., check local listings).

The Jimmy Fallon-hosted “Saturday Night Live” (NBC, 11:30 p.m.) is rerun, with Michael Buble as musical guest.
