The destruction of the Brazilian rain forest...

The destruction of the Brazilian rain forest has become such a key symbol of ecological waste that there seems something forced about the premise in the 1992 Medicine Man (KTLA Tuesday at 8 p.m.) Sean Connery, looking like a cross between the Ginger Man and Tarzan, is fun as a pharmaceutical hermit; Lorraine Bracco is a little shrieky as his partner-antagonist, and director John McTiernan makes the trees look gorgeous.

Suspenseful though rambling, the 1992 TV movie To Catch a Killer (KTLA Thursday at 8 p.m.) stars Brian Dennehy, convincingly menacing and maniacal as serial killer John Wayne Gacy.

Writer-director Heywood Gould’s 1991 One Good Cop (KTLA Friday at 8 p.m.) plays like a mix of “Hill Street Blues,” “Kindergarten Cop” and “Kramer vs. Kramer.” In its own way it hammerlocks you into an emotional response. Michael Keaton stars as a New York police detective whose widowed partner is killed in a shootout, leaving Keaton the legal guardian of his three daughters.

The Enforcer (KCOP Saturday at 8 p.m.), Clint Eastwood’s third “Dirty Harry,” is arguably the best. To be sure, Eastwood’s Harry Callahan, veteran San Francisco Police Department homicide inspector, is just as tough and ornery as ever, but this time he’s been presented with an unprecedented degree of humor. Tyne Daly is Harry’s latest partner, who proves her mettle and then some to the macho Harry.

Doctor Zhivago, (KCET Saturday at 9 p.m.) David Lean’s beautiful but ponderous 1965 epic film of the Boris Pasternak novel.
