Tune In Tonight: Wedding bells ring on ‘30 Rock’

Look for a hesitant, postfeminist and self-consciously ridiculous walk down the aisle by Liz Lemon tonight as “30 Rock” (7 p.m., NBC) hurtles through its deliriously silly final season. Then again, the same could be said of the first.

• Bob Hope and Katharine Hepburn as you’ve (probably) never seen them: together! A Soviet pilot (Hepburn) falls for an American Air Force officer (Hope) in the curious 1956 Cold War relic “The Iron Petticoat” (7 p.m., TCM). Janet Leigh and John Wayne starred in a similar movie, “Jet Pilot,” which was shot in 1950 but not released until 1957 because producer Howard Hughes, suffering from mental illness, would not let the film out of his hands. Both strange efforts were loosely based on “Ninotchka” (12:30 a.m., TCM).

A comedy made in Britain, “Petticoat” sparked a public feud between Hope and screenwriter Ben Hecht, who thought that Hope’s gag writers had ruined his script and that his editors had all but removed Hepburn from the film. As a result, “The Iron Petticoat” has been screened only twice in the United States since its original theatrical release. Tonight marks its television debut.

• The new true-life re-enactment series “Panic 9-1-1” (9 p.m., A&E) recalls harrowing conversations between crime victims (or people who think they are about to become victims) and police dispatchers.

In addition to re-enactments, each segment includes interviews with witnesses, police officers, call dispatchers and, sometimes, the callers. The narrative keeps viewers guessing which potential victims will survive. Their fates remain a mystery until the end.
