The 1984 Purple Hearts (KCOP Sunday at 5 p.m.) seems a deliberate, if pale, carbon copy of “An Officer and a Gentleman.” This is an old-fashioned, all-stops-out romance between a Marine Corps doctor (Ken Wahl) and a Navy nurse (Cheryl Ladd), played out against the Vietnam War.

The all-time popular The Sound of Music (NBC Sunday at 8 p.m.), a 1965 blockbuster, winner of five Oscars and from the final Rodgers and Hammerstein musical, stars, of course, Julie Andrews in the story of the Trapp Family Singers, who fled their home in the Austrian Alps just before the outbreak of World War II.

It’s too bad that so much of the 1985 Target (KTLA Sunday at 8 p.m.) is a conventional spy thriller with high-speed chases, because at its heart it is an honest father-and-son estrangement drama that comes to a boil when the father (Gene Hackman), a Dallas businessman, resumes secret agentry after 20 years. Matt Dillon plays the son.

Pale Rider (ABC Sunday at 8:30 p.m.) is Clint Eastwood’s 1985 variation on “Shane,” a pleasant enough diversion but marred by the queasy development that finds a pretty teen-ager (Sydney Penny) trying to seduce Eastwood’s grizzled Stranger, who’s come out of nowhere to help some gold prospectors in their fight with a ruthless hydraulic mining company.

In Fire and Rain (KTLA Monday at 8 p.m.), there’s little of either quality. The mediocre 1989 cable movie is about the crash of Delta Airlines Flight 191 at Dallas-Fort Worth on Aug. 2, 1985. Angie Dickinson plays a nurse and Charles Haid and Dean Jones play rescue workers, but in a sense they’re victims, too.

The Dreamer of Oz: The L. Frank Baum Story (NBC Tuesday at 8 p.m.), a 1990 TV bio-pic about the author of the children’s book that inspired the 1939 film classic “The Wizard of Oz,” is long on mush and short on magic. John Ritter plays the title role as a one-dimensional bobo of such unfaltering goodness that he makes Mister Rogers look like the Marquis de Sade.

The 1991 Double Impact (KCOP Thursday at 8 p.m., Saturday at 6 p.m.) offers two Jean-Claude Van Dammes for the price of one, and for fans of the Belgian-born martial arts star, it delivers the goods. It’s a fast-moving action-adventure set largely in Hong Kong, where in 1966 a couple of bad guys assassinated a British entrepreneur and his wife, but the twin sons survive--separately, of course. They meet as adults who join forces in avenging their parents’ death. Van Damme does well in playing two sharply defined and distinct individuals.

The Enforcer (KCOP Saturday at 8 p.m.), Clint Eastwood’s third and often humorous “Dirty Harry” movie that was made in 1976, tracks down an elusive terrorist group. To Harry’s dismay, he has a new partner--none other than Tyne Daly, later of “Cagney and Lacey.”
