No one can say there’s a lack of variety in the movies airing Sunday night. There’s Katharine Hepburn in the new TV movie Mrs. Delafield Wants to Marry (CBS, 9-11 p.m.), playing a widow whose romance (with Harold Gould) shocks their offspring. Meanwhile on ABC (7-11 p.m.), Charlton Heston once again parts the Red Sea in Cecil B. DeMille’s The Ten Commandments, and Barbara Eden returns as the genie of the 1965-70 TV series in a repeat of I Dream of Jeannie: 15 Years Later on NBC (9-11 p.m.). Here, she’s attempting to save her mortal marriage to astronaut Wayne Rogers from the machinations of her evil genie sister, also played by Eden.

There are three more movies on Monday at 9 p.m. Ann Jillian plays identical twins trapped in a lethal game of mistaken identity in Killer in the Mirror (NBC), a new TV movie remake of Bette Davis’ lurid 1964 “Dead Ringer.” Barry Bostwick, Joanna Cassidy, Linda Purl and Tracy Nelson star in another new TV movie, Pleasures (CBS), which tells of three women who reach a romantic turning point in their lives in the course of one summer. Then there’s a reprise on Channel 2 of The Burning Bed, the 1984 TV movie that brought Farrah Fawcett much praise for her impressive portrayal of Francine Hughes, a real-life battered wife.

Starting Monday with Shadow of a Doubt, Alfred Hitchcock’s personal favorite among his films, Channel 13 is airing a week of Hitchcock classics at 8 nightly.

An Oscar-nominated short documentary, Deborah Shaffer’s fine, provocative Witness to War: Dr. Charlie Clements (Channel 28 Tuesday at 10 p.m.) tells of a one-time Vietnam pilot, a man who was graduated top of his class from the Air Force Academy, who became a doctor behind rebel lines in El Salvador.

In News at Eleven (CBS Wednesday at 9 p.m.), Martin Sheen is cast as a local TV anchorman whose moral and ethical standards are tested when his ambitious news director sensationalizes a story in order to boost the station’s ratings. The story involved is about an alleged sexual involvement between a high school teacher and a girl student. Peter Riegert is the news director and Barbara Babcock is a deputy D.A. investigating the case.

The most rewarding gift Barry Levinson’s Diner (ABC Thursday at 8 p.m.) gives us is the honest recapturing of our past. A fresh and personal wonder, it rescues memories of the late ‘50s and early ‘60s from TV’s high gloss and lets them stand, tender and real. Steve Guttenberg, Daniel Stern, Mickey Rourke and Kevin Bacon are the guys who hang out at a Baltimore diner as they cope with coming of age, and they are all heartbreakingly believable.

Bob Rafelson’s The King of Marvin Gardens (Channel 5 Friday at 8 p.m.) may still seem as pretentious as it did when it was made in 1972, yet its many virtues linger in memory. Set in a decaying, inevitably symbolic Atlantic City not yet revived by gambling, it stars Bruce Dern as a flamboyant, self-deceiving promoter with a blowsy wife (Ellen Burstyn) and a beautiful, fragile stepdaughter (Julia Anne Robinson). Jack Nicholson is Dern’s brother, a storyteller on an all-night Philadelphia FM station, another fantasizer but, unlike Dern, one who recognizes his fantasies as antidotes to a real world he knows and fears. Written by Jacob Brackman, at that time Esquire’s film critic, it has at its heart the confrontation between the two very different brothers. The cast, which includes Scatman Crothers as a gambling boss for whom Dern is fronting, is superb, as is Laszlo Kovacs’ cinematography.

Airing Friday at 9 p.m. on Channel 11, The Next Man is a familiar, less-than-riveting international intrigue starring Sean Connery as a peace-loving Saudi Arabian diplomat with whom erstwhile hitlady Cornelia Sharpe becomes involved.

Robert Conrad stars in the new TV movie Charley Hannah (ABC Saturday at 8 p.m.), playing a policeman who mistakenly kills a youth while pursuing some cop killers but gets a chance to redeem himself by taking in a troubled kid (played by Conrad’s real-life son Shane) who may have witnessed the slayings.

The slapdash Caddyshack repeats Saturday at 9 p.m. on CBS. Michael O’Keefe is the young caddy at a Midwestern country club desperate to win its college scholarship but faced with coping with its oddball members (Chevy Chase, Rodney Dangerfield, etc.) and its crazy groundskeeper (Bill Murray). A nifty premise is done in by too much silliness and condescension.

The fine Western Angel and the Badman, in which gunslinger John Wayne is reformed by Quaker Gail Russell, airs Saturday at 10 p.m. on Channel 28.
