WEEKEND TV : HEARTS AND FLOWERS, THEN ‘AMERIKA’

Television is giving a new twist this weekend to the adage that “all’s fair in love and war.” A spate of Valentine’s Day specials today gives way Sunday to the premiere of ABC’s disputatious miniseries “Amerika.”

The Valentine’s programming today includes “Be My Valentine, Charlie Brown,” a “Peanuts” cartoon originally broadcast in 1975, (8 p.m. on Channels 2 and 8), and “Valentine,” a 1979 TV movie about a late-blooming romance between characters played by Mary Martin and Jack Albertson (9 p.m., Channel 11).

Cable TV also is getting into the act. The Disney Channel is serving up a collection of romantic moments from his classic cartoons in “A Valentine From Disney” at 5 p.m. Showtime checks in at 8 p.m. with a new movie in its Harlequin Romance series, “Cloud Waltzing,” with Kathleen Beller.

Sunday brings the first installment of “Amerika,” the seven-part miniseries that speculates what life in the United States would be like 10 years after a takeover by the Soviet Union. The first show runs from 9 to 11:20 p.m. (Channels 7, 3, 10 and 42), with subsequent episodes Monday through Friday and the following Sunday.

NBC is countering with “The Facts of Life Down Under,” a two-hour edition of “The Facts of Life” that was shot in Australia (9 p.m., Channels 4, 36 and 39). CBS (Channels 2 and 8) will stick with its regular series: “Designing Women” at 9 p.m., “Nothing Is Easy” at 9:30 p.m. and “Hard Copy” at 10 p.m..
