The 1990 Air America (KTLA Monday at 8 p.m., again Saturday at 6 p.m.), which stars Mel Gibson and Robert Downey Jr., is about the CIA’s secret airline operating in Laos in 1969. As long as this 1990 film is racking up its absurdist points it’s a sporty, free-wheeling entertainment, but unfortunately it lacks focus.

The Terminator (KCOP Thursday at 8 p.m.) is a stylish, ultra-gory and ultimately empty science-fiction adventure starring Arnold Schwarzenegger in the title role as a huge, deadly cyborg who has been transported from the future to stalk an unlikely prey, a scatter-brained waitress (Linda Hamilton).

Top Gun (KCOP Friday at 8 p.m.) is that wildly popular 1986 picture, allegedly based on the Navy’s crack fighter pilot program, it sucks us into a high-tech world of multimillion-dollar aircraft and hell-for-leather fliers. Tom Cruise stars, along with Kelly McGillis, Val Kilmer and Anthony Edwards.

As in the 1987 original, Lethal Weapon 2 (CBS Friday at 8:30 p.m.) has Mel Gibson and Danny Glover as a cop team, but this 1989 sequel is outrageously over-scaled and has the brain-rattling pace of a terminal speed freak going in the wrong direction on a freeway.

The hopped-up, gaseous 1986 Cobra (KCOP Saturday at 6 p.m.), starring Sylvester Stallone as a cop who’s become a one-man hit squad, is a lurid, ludicrous, exhausting, enervating bloody mess thundering at you in vast close-ups.

Graveyard Shift (KTLA Saturday at 8 p.m.) is silly piece of 1990 horror schlock derived from an early Stephen King story and set in a derelict Maine textile mill, overseen by Stephen Macht’s Simon Legree foreman and featuring Brad Dourif as a spacey rat exterminator.

Witness (KCOP Saturday at 8 p.m.), Peter Weir’s absorbing 1985 film, finds Harrison Ford as a Philadelphia cop hiding out with the Amish, where he and Kelly McGillis’ widow find themselves attracted to each other.

Veteran Japanese director Juzo Itami made his 1985 directorial debut with the sly, often outrageous satire The Funeral (KCET Saturday at 9 p.m.), which chronicled the shenanigans surrounding an elaborate traditional Japanese service.

On the late show: The Boys from Brazil (KABC Saturday at 11:30 p.m.) defies credibility on the screen with its eerie notion that an entire generation of Hitlers could be cloned from the long-dead original, but Gregory Peck is a chilling Dr. Josef Mengele, and Laurence Oliver is an impressive Nazi hunter.
