The new TV movie Side by Side...

The new TV movie Side by Side (CBS Sunday at 9 p.m.) teams Milton Berle, Sid Caesar and Danny Thomas as three men who refuse to be labeled “old.”

In the Heat of the Night (NBC Sunday at 9 p.m.) is a TV-movie sequel to the Oscar-winning film of the same name. Carroll O’Connor and Howard Rollins play the Southern redneck sheriff and the smart big-city police detective created by Rod Steiger and Sidney Poitier.

Longarm (ABC Sunday at 9:30 p.m.) is a new made-for-TV comedy-Western starring John T. Terlesky as a U.S. marshal who has adventures with pretty women as well as colorful outlaws.

Laura Lansing Slept Here (NBC Monday at 9 p.m.) stars Katharine Hepburn as a flamboyant, world-famous novelist who tries to prove she can still lead a normal life by moving in with a typical middle-class family. This new TV movie reunites Hepburn with her “Mrs. Delafield Wants to Marry” director George Schaefer and its writer, James Prideaux.

Parker Stevenson stars in the series pilot-TV movie Probe (ABC Monday at 9 p.m.) as an eccentric supersleuth who traces a series of murders to a computer programming error.

Fun With Dick and Jane (Channel 11 Monday at 8 p.m.) isn’t. Starring George Segal and Jane Fonda, this dull-edged 1977 satire on upper-middle-class unemployment, with its acid comment on contemporary morality, is an instance of a good idea badly botched by crass humor and invention.

Channel 5 is presenting a week of horror pictures in its 8 p.m. movie slot, beginning Monday with The Omen and its two sequels, The Amityville Horror (Thursday) and--best of the bunch--The Entity (Friday), a 1983 thriller of the supernatural starring Barbara Hershey as an already struggling single parent besieged by a malevolent power and eventually caught in a battle between psychiatrists and parapsychologists.

Revenge of the Nerds (Channel 11 Tuesday at 8 p.m.) is a delicious, gratifying underdog fantasy and a raunchy, uproarious satire set in the often cruel and inherently discriminating world of college fraternities and sororities. Robert Carradine and Anthony Edwards are the nerds, off to college with boundless naivete, terrible haircuts, ugly glasses and too many pens and pencils bulging the pockets of their short-sleeved shirts.

Falling in Love (Channel 13 Tuesday at 8 p.m.) is a variation on “Brief Encounter” starring Robert De Niro and Meryl Streep as suburban Manhattanites married to others but who become emotionally entangled in spite of themselves. This handsome and intimate 1984 film may actually play better on the tube; on the big screen it seemed too conventional for such distinctive superstars.

Shattered Innocence (CBS Wednesday at 9 p.m.), a new TV movie based on an actual incident, stars Jonna Lee as a small-town Kansas cheerleader who winds up an ill-fated porno star. Melinda Dillon, John Pleshette and Kris Kamm co-star.

The 1984 film Mass Appeal (Channel 5 Saturday at 8 p.m.) is a stilted version of the Bill C. Davis play which pits Jack Lemmon’s tippling, disillusioned priest against fiery seminary gadfly Zeljko Ivanek. You can imagine it playing well on the stage, but it seems mechanical on the screen. Not helping matters is that we’ve seen Lemmon’s witty, burnt-out bravura turn once too often. Charles Durning, who’s flinty and perfect, plays the ultra-conservative local monsignor.
