Hang ‘Em High (Channel 13 Sunday at 8 p.m.), a 1968 Western that is as savage as it is well-made, stars Clint Eastwood as a former St. Louis lawman whose unwitting purchase of stolen cattle threatens his life.

Almost Grown (CBS Sunday at 9 p.m.) is a new TV movie dealing with a New Jersey couple (Timothy Daly, Eve Gordon), starting with their courtship in the ‘60s, that also is launching a series (Monday at 10 p.m.).

The new TV movie In the Line of Duty: The FBI Murders (NBC Sunday at 9 p.m.) chronicles a six-month search for two maniacal killers (Michael Gross, David Soul).

Another new TV movie, Disaster at Silo 7 (ABC Sunday at 9 p.m.), tells of an Air Force technician (Michael O’Keefe) racing against time to prevent a devastating explosion at a U.S. missile site. Perry King and Dennis Weaver co-star in this drama, inspired by an actual incident.

Shootdown (NBC Monday at 9 p.m.), a new TV movie also based on a true story, stars Angela Lansbury as a mother searching for the truth surrounding her son’s death in the 1983 downing of Korean Air Lines Flight 007.

Apocalypse Now (Channel 5 Tuesday at 7 p.m.) is a bold, daring, landmark film that attempts to rework Joseph Conrad’s “The Heart of Darkness” as a saga of the Vietnam War. Although the 1979 production finally succumbs to the bewildering madness of war it so dazzlingly depicts, it is nonetheless a rich, challenging experience. Martin Sheen stars as a burnt-out agent assigned to travel upriver from Saigon to find the near-mythical Kurtz (Marlon Brando), a Special Forces officer driven mad apparently by the unique cruelty and complexity of the war.

The Delta Force (NBC Tuesday at 9 p.m.), a 1986 Chuck Norris movie, is a standard hijack-hostage adventure in which the intricate logistics involved in the film’s making are far more impressive than its script.

Made in 1979, The China Syndrome (Channel 5 Wednesday at 7:30 p.m.) proved to be one of the most prophetic films ever made, having been released shortly before the Three Mile Island catastrophe. At once a fervent anti-nuclear protest and an edge-of-the-seat thriller, it stars Jane Fonda as a bubbly TV reporter and Michael Douglas as her cameraman. They’re doing a routine gee-whiz feature at a nuclear power plant when an accident occurs.

The 1985 That Was Then, This Is Now (Channel 13 Wednesday at 8 p.m.) is a nice, sincere “little” film about two delinquents (Emilio Estevez, Craig Sheffer); Estevez also adapted the script from an S.E. Hinton novel.

The lively 1984 Runaway (CBS Wednesday at 9 p.m.), a Michael Crichton “science-fact” adventure, stars Tom Selleck and imagines the worst possible kind of handgun, one that shoots microelectronic bullets that are all but impossible to escape.

Gotcha! (Channel 5 Thursday at 8 p.m.) takes its title from a silly campus game in which students shoot paint pellets at each other. The idea is to introduce the film’s 18-year-old hero (Anthony Edwards) and swoop him up into some foreign intrigue in which the bullets become all too real. Unfortunately, the 1985 release misfires from too much crassness.

The House on Garibaldi Street (Channel 9 Saturday at 8 p.m.) is a powerful, step-by-step 1979 TV movie reenactment of the abduction of top Nazi war criminal Adolf Eichmann in Argentina by Israeli agents. It’s adapted by Steve Shagan from the book by Isser Harel (played by Martin Balsam), who directed the perilous mission.
