When news came out last week about the end of “Desperate Housewives” after the coming season, there wasn’t much talk of Nicollette Sheridan, whose departure as Edie Britt was followed by a scathing lawsuit against its makers.

Those wondering what happened to Sheridan need only tune into another one of those dull, utterly predicatable romantic films on Hallmark. In “Honeymoon for One” (Hallmark, 9 p.m.), she stars as an overworked ad executive who breaks up with her scheming finance and decides to go on the honeymoon they planned anyway.

While there, in picturesque Ireland, she meets a rugged guy who at first she is at odds with. When he finds out she represents the company that was going to bespoil their land, though, it’s a complication.

The strangest things about these romantic films is not the lack of romance, but how the soundtrack just minces along on its own, seemingly having nothing to do with the action on screen.

In the other new movie on cable tonight, When the world is threatened by a looming catastrophe, it’s up to an archaeologist and a book editor to save the world in “Doomsday Prophecy” (Syfy, 9 p.m.). A.J. Buckley and Jewel Staite star. No, I don’t know them either.

Speaking of such, it won’t be as entertaining as Thursday’s debate, but it may be more consequential: The Iowa Straw Poll (Fox News, 5 p.m.) from Ames, with Republicans vying for position on the network built by and for Republicans.

If you’re keeping up with the Saturday night repertoire of Harry Potter films, it’s already up to 2007 and “Harry Potter and the Order of the Phoenix” (ABC, 8 p.m.).

How bad is Summer TV? How about a primetime compendium of highlights from “Wrestlemania XXVII” (NBC, 9 p.m.), held four months ago at the Georgia Dome in Atlanta. Among its stars were The Rock and Snooki.

Gnarls Barkley and Thievery Corporation play a repeat of “Austin City Limits” (PBS, 9 p.m., check local listings).

An overview of Matt Smith’s reign as Doctor Who is reviewed on “Best of the Doctor” (BBC America, 9 p.m.).

What to look for when selling your gold jewelry on “The Suze Orman Show” (CNBC, 9 p.m.).

Katherine Heigl and Josh Duhamel star in yet another romantic comedy, “Life as We Know It” (HBO, 8 p.m.) from last year. Other cable moies tonight include Kristen Bell, Jamie Lynn Curtis and Sigourney Weaver in “You Again” (Starz, 9 p.m.) and the 2010 remake of “The A-Team” (Cinemax, 10 p.m.) with Liam Neeson and Bradley Cooper.

We don’t need another hero. Nevertheless: “Mad Max Beyond Thunderdome” (AMC, 10 p.m.).

The country queen may seek a D.I.V.O.R.C.E. from her abode in “Loretta Lynn’s Haunted Plantation” (Travel, 8 p.m.).

Jimmy Stewart is the star all day on Turner Classic Movies, with “Mr. Smith Goes to Washington” (9 a.m.) this morning and “The Shop Around the Corner” (2:30 p.m.), the basis for “You’ve Got Mail” years later, this afternoon. Tonight, it’s “The Man Who Shot Liberty Valance” (8 p.m.), “No Highway in the Sky” (10:15 p.m.), “Anatomy of a Murder” (midnight), “The Murder Man” (2:45 a.m.) and “The Stratton Story” (4 a.m.). That’s right: Not only no “It’s a Wonderful Life,” no “Vertigo” or “Rear Window” either.

Jesse Eisenberg hosts a rerun of “Saturday Night Live” (NBC, 11:30 p.m.) just in time to plug his new movie. Nicki Minaj is musical guest.
