To prepare for Sunday’s second season premiere, the Emmy-winning first season of “Homeland” (Showtime, noon) is rerun in a 12 hour marathon. Subscribe and see what all that Emmy fuss was even as you prepare for season two.

Sure beats the day-long marathon of “Jersey Shore” (MTV, 2 p.m.). The network is showing all 59 episodes of the first five seasons leading up to the start of the sixth and final season Thursday.

Saturday night is a night for football on broadcast TV – Wisconsin at Nebraska (ABC, 8 p.m.) and Texas at Oklahhoma State (Fox, 8 p.m.).  Either that or it’s a night for same-week reruns: of the premieres of “Vegas” (CBS, 8 p.m.) and “Elementary” (CBS, 9 p.m.); the second episode of “Revolution” (NBC, 8 p.m.) and two hour season premiere of “Law & Order: Special Victims Unit” (NBC, 9 p.m.).

I kind of miss his oddball comedy show. So here’s a special: “Demetri Martin, Standup Comedian” (Comedy Central 10 p.m.).

It’s the season finale for now of “Doctor Who” (BBC America, 9 p.m.) and the adventures in the U.S. end in New York where the Weeping Angels return.

Robert Englund, the original Freddy Krueger, stars in the new cable B-movie “Lake Placid: The Final Chapter” (Syfy, 9 p.m.) about battling giant hungry crocodiles.

Also new, a high school junior gets obsessed with the new girl at school in “A Mother’s Nightmare” (Lifetime, 8 p.m.).

New movies on premium cable include Jonah Hill as “The Sitter” (HBO, 8 p.m.), Daniel Craig in “The Girl with the Dragon Tattoo” (Starz, 9 p.m.) and Jon Voight in “Beyond” (Cinemax, 10 p.m.).

The trouble with “Bayou Billionaires” (CMT, 9 p.m.) is that they are bored. So Chantel and Albert go to beauty school to learn how to groom dogs; Gerald and Thomas are moved to build the largest mailbox in Louisiana.

It’s Mario Batali vs. Tony Liu on a new “Iron Chef America” (Cooking Channel, 9 p.m.).

Jamie Oliver presents “Chef Race: U.K. vs. U.S.” (BBC America, 10 p.m.) featuring 16 chefs racing from Los Angeles to Las Vegas.

Several people have had bad things happen while exercising, on the self-explanatory “I Was Impaled” (Discovery Fit & Health, 10 p.m.). Similarly, a neo-Nazi explains how “I (Almost) Got Away with It” (Discovery, 10 p.m.).

“Redneck Rehab” (CMT, 10 p.m.) isn’t what I thought it was going to be at all. Instead of saving people with mullets, it brings those elite city types back to their rural origins and gets them to get off their high horse and try riding some 3-wheelers in the mud. Tom Arnold, some kind of network redneck emissary, is host.

“48 Hours” (CBS, 10 p.m.) begins its 25th season. Remember when Dan Rather hosted and it wasn’t always bout a lurid murder case?

In the world of Saturday morning animation, new seasons start for “Star Wars: The Clone Wars” (Cartoon Network, 9:30 a.m.), “Green Lantern: The Animated Series” (Cartoon Network, 10 a.m.) and “Young Justice” (Cartoon Network, 10:30 a.m.).

Lots of popular film favorites on today, including “Titanic” (HBO2, 5:45 p.m.), “Napoleon Dynamite” (IFC, 8 p.m.), “Aladdin” (ABC Family, 8 and 10 p.m.) “School of Rock” (Flix, 8 p.m.), “True Lies” (Encore, 8 p.m.) and “Mean Girls” (VH1, 9 p.m.).

Choose your Tarantino: “Pulp Fiction” (More Max, 9 p.m.) or  “Kill Bill, Vol. 1” (Bravo, 9 pm.) play opposite one another.

A handful of Ralph Richardson films run tonight on Turner classic Movies: “The Fallen Idol” (8 p.m.), “Anna Karenina” (10 p.m.), “The Four Feathers” (midnight), “The Wrong Box” (2 a.m.) and “The Looking Glass War” (4 a.m.).

Other football tonight includes Florida State at South Florida (ESPN, 6 p.m.), South Carolina at Kentucky (ESPN2, 7 p.m.), Towson at LSU (ESPNU, 7 p.m.) Mississippi at Alabama (ESPN, 9:30 p.m.), Oregon at Washington State (ESPN2, 10:30 p.m.) and Grambling State at Alabama A&M (ESPNU, 10:30 p.m.).

Neil Young and Crazy Horse, Foo Fighters, the Black Keys and Band of Horses play the “Global Festival: Live from Central Park” (Fuse, 5 p.m.).

Arcade Fire plays a rerun of “Austin City Limits” (PBS, 9 p.m., check local listings) and also appears on a replay of  “Saturday Night Live” (NBC, 11:30 p.m.). Last season’s finale with Mick Jagger as host included a number of various musical aggregations including Jeff Beck and Foo Fighters. The show was also the sendoff for Kristen Wiig.
