WORTH NOTING ON TV

SATURDAY

Monstervision (TNT, beginning 8 p.m.): Science fiction of the serious sort was a big thing a few decades ago on TV. One of the best-loved of all the series in this genre was `The Outer Limits,' which aired from 1963 to 1965 and was a significant step in the medium's progression to `Star Trek' and its spinoffs. This all-night recap of that series marks the fifth edition of TNT's monthly looks at TV's worthwhile sci-fi shows of the past. It includes early performances by actors like David McCallum, Sally K ellerman, and Marion Ross, as well as talks with the series' originators, Leslie Stevens and producer-writer Joseph Stefano. You'll also see the work of Oscar-winning cinematographer Conrad Hall. SUNDAY

Alan King: Inside the Comedy Mind (Comedy Central, 11:30 p.m.): A talk with Robin Williams tends to be mercurial, improvisational, utterly unpredictable for the viewer and, I suspect, uncontrollable for the interviewer. The result is more performance art than traditional interview, as his brilliant comic sense sends him off into impressions and mini-sketches. But he can also be reflective. In this talk with another comedian of a different breed - Alan King - Williams is both. We get a stream of impressi ons (Peter Lorre as a baseball announcer, for instance), but also recollections of his days in private schools and at the Juilliard school, as well as a discussion of his work in films like `Popeye,' `The World According to Garp,' `Good Morning, Vietnam,' and others. Comedy Central, by the way, says it took two years and four talent coordinators to get the tightly scheduled Williams to sit long enough for such an extended talk. The result makes an appropriate start for this series' new season.

Booknotes (C-Span, 8-9 p.m.): The guest is Kay Mills, author of `This Little Light of Mine: The Life of Fannie Lou Hamer.'
