Great Wonders of the World (Disney channel, 8-9 p.m.): Certain natural and man-made sites seem to be inexhaustible subjects for TV. "Wonders of Nature," the first of three weekly specials, offers memorable vistas of Igaszu Falls in Brazil and Argentina, the Grand Canyon of the United States, Australia's Ayers Rock, Tibet's Himalyas, Brazil's Amazon River, and the Sahara Desert and the Serengeti Plain of Africa (never mind how many times you've seen the latter on TV - it still impresses). Foreign Affairs (TNT, 8-10 p.m.): Joanne Woodward stars in a made-for-TV film based on the Pulitzer Prize-winning novel by Alison Lurie. Vinnie - a quiet, late-middle-aged American college professor - is on a plane to Britain when she meets her opposite: a talkative American engineer who seems distictly below her level intellectually. Standoffish at first - perhaps disdainful - this Anglophile has moderated her glorified image of Britain by the time the drama is over, and has also learned not to be quite s o judgemental about others. The Oklahoma sewer engineer who wins her over is played Brian Dennehy, in a cast that includes Ian Richardson and Stephanie Beacham. * FRIDAY
Reed Royalty (Bravo channel, 10-11 p.m.): Musician and jazz expert Branford Marsalis explores the history of jazz in the two-part special beginning here. He acts as host and performs an original solo on each show. `Reed Royalty' deals with the clarinet and the improvisational brilliance of its jazz players. Vintage footage from the 1930s and 1940s - featuring performances by Artie Shaw, Woodie Herman, and Benny Goodman - is complemented with some insightful words by Marsalis. (On April 2, `Tenor Tit ans' completes this version of the jazz story with a lively history of the tenor saxophone).
