WORTH NOTING ON TV

* SUNDAY

Seven Wonders of the World (The Learning Channel, 7-11 p.m.): They have loomed large in legend and history, even though only one of them - the pyramids of Egypt - still exists.

In this four-part back-to-back program, historian John Romer takes viewers on a visit to each wonder. He explains how they were built and - through archaeology and other forms of research - how we know what the world was like at the time. With computer graphics, each ruin is reconstructed to appear as it may have then, and Romer shows how these impressive achievements influence architecture today.

In case they aren't on the tip of your tongue, the other six wonders are: the Lighthouse (Pharos) at Alexandria; the Hanging Gardens of Babylon; the Mausoleum at Halicarnassus; the Colossus of Rhodes; the temple of Artemis at Ephesus; and the Statue of Zeus at Olympia.

* MONDAY

American Cinema (PBS, 9-11 p.m.): Why do some films affect us so deeply? Why do some people walk around with favorite movie scenes lurking in the back of their minds?

In trying to answer such questions, this probing, 10-part series interviews actors, directors, executives, screenwriters, historians, and many other specialists. Archival clips, photos, and other items are used.

The exploration ranges from anecdotes to technical explanations as the series looks at the complex process of moviemaking as an art form, industry, and pop-cultural sign of the times.

The opener, ``The Hollywood Style,'' shows how Hollywood's cinematic style - in everything from acting to editing - creates story and character. Sydney Pollack, Martin Scorsese, and other directors are interviewed.

Yes, there are plenty of memorable clips from such films as ``Casablanca,'' ``Scarface,'' and ``The Age of Innocence.''

Programs two through four air Jan. 30, Feb. 13, and Feb. 20.
