Weekend TV : It’s Time for Final Bows on ‘Family Ties,’ ‘Moonlighting,’ ‘War and Remembrance’

Curtain calls galore highlight Sunday night’s TV schedule as two trend-setting series and the longest and most expensive miniseries of all time take their final bows.

NBC’s “Family Ties” unravels in a special 70-minute episode beginning at 8 p.m. Sunday (4)(36)(39) as Alex (Michael J. Fox) finally leaves home for a high-powered job on Wall Street after seven seasons of wisecracks and tears in the Keatons’ Columbus, Ohio, kitchen. The final show includes a curtain call featuring hugs and goodbys from the entire cast. As a preview to the end, KTTV Channel 11 will air the very first episode of the series Sunday at 6 p.m.

In a less ballyhooed finale, the once-proud cast of “Moonlighting,” plagued this season by dismal ratings, will also bid farewell Sunday at 8 p.m. (7)(3)(10)(42). The razor-tongued Bruce Willis and Cybill Shepherd, once the daring darlings of television, star for the last time.

And with the death of F.D.R., Hitler’s suicide and the collapse of the Third Reich, the 29 1/2-hour saga of the Henry family, “War and Remembrance,” draws to a climactic conclusion Sunday at 9 p.m. on ABC (7)(3)(10)(42).

For those with an eye toward current history, Cable News Network will offer live coverage of Soviet President Mikhail S. Gorbachev’s visit to China beginning Sunday at 2 p.m.
