The 1985 Mask (KTLA Sunday at 8 p.m.) forthrightly introduces us to a San Fernando Valley 15-year-old, beautifully played by Eric Stoltz, and allows us to get used to his cruelly disfigured face until we discover what is really exceptional about him: his levelheadedness and sweet spirit. Starring a ferociously fine Cher.

Close Encounters of the Third Kind (KCOP Sunday at 8 p.m.) is Steven Spielberg’s magical and mystical 1977 science-fiction film about UFOs. Richard Dreyfuss is a power company worker who leaves home to discover what has blacked out half the state, and Melinda Dillon plays a mother searching for her young son, who has run off to join the alien beings.

The slick, violent 1990 Kindergarten Cop (NBC Sunday at 8:30 p.m. and Friday at 8:30 p.m.) unveiled the kinder, superficially gentler Arnold Schwarzenegger as an undercover police officer who winds up teaching little kids as part of his job.

Revenge of the Nerds (KTTV Monday at 8 p.m.) is a delicious, gratifying 1984 underdog fantasy and a raunchy, uproarious satire set in the often cruel and discriminating world of college fraternities and sororities. Robert Carradine and Anthony Edwards star.

My Tutor (KTTV Wednesday at 8 p.m.), a disarming, lightweight 1983 coming-of-age comedy, stars Matt Lattanzi as a Southern California rich kid who falls in love with a beautiful woman (Caren Kaye) hired to help him conquer French.

In the deep outer space of Ridley Scott’s 1979 chiller Alien (KTLA Thursday at 8 p.m.), a slimy primordial past confronts the sleek technological tomorrow. Among the earthlings at peril is a resourceful and resilient Sigourney Weaver.

Never mind that the recently released director’s cut of Ridley Scott’s influential 1982 futuristic film noir epic Blade Runner (KTLA Friday at 8 p.m.) has revealed a movie as substantial as it is stylish; what you’ll see here is a 94-minute version with, of course, commercial interruptions. Harrison Ford stars as an ex-cop bounty hunter in pursuit of lifelike robots that turn deadly.

Beverly Hills Cop (ABC Saturday at 9 p.m.), the 1984 Eddie Murphy smash hit, is a sleek, overly violent high-style Hollywood entertainment that may just seduce you in spite of yourself. Murphy plays a sassy, streetwise Detroit cop set down in the lush hills of Beverly.

Twenty-one years ago, Shaft (KCET Saturday at 9 p.m.), starring Richard Roundtree as a private eye, launched a whole cycle of so-called violent (and sexy) “blaxploitation” pictures; few, if any, were as effective as the original.
