At the recent private memorial to Bette Davis, James Woods spoke of the lasting impact upon him of the “naked emotion� Davis expressed in one of her most popular pictures, the 1942 Now, Voyager (Channel 13 Tuesday at 8 p.m.). The film is often regarded as high-grade soap opera yet amazingly potent still, thanks to Davis’ vulnerable and selfless performance as the repressed Boston spinster Charlotte Vale rescued by her suave psychiatrist (Paul Henried), who figures in the film’s memorable cigarette lighting scene.

The Christmas Gift (CBS Tuesday at 9 p.m.) is an all-too-typical Yuletide TV movie, a simplistic and manipulative tale which asks us to believe that of all people John Denver, cast as an architect for a major New York development company, would consider selling out a quaint Colorado mountain town to build a condominium-packed ski resort.

Reportedly, Bob Clark, director of “Porky’s,� had for years wanted to make a film of humorist Jean Shepherd’s short story, “The Red Ryder Nails the Cleveland Street Kid.� The result is a kind of grade-school “Porky’s� minus the raunchiness. There’s little of Shepherd’s legendary subversive humor is what is essentially a sitcom set in the late ‘30s starring little Peter Billingsley, who dreams of owning an elaborate rifle; Darren McGavin and Melinda Dillon are his parents.

The 1951 version of Damon Runyon’s The Lemon Drop Kid (Channel 11 Thursday at 8 p.m.) is one of Bob Hope’s best pictures, in which he plays a race track habitue in big debt to a gangster.
