Weekend TV : Documentary Charts Changes in Kids’ Lives; Four-Way Battle Looms in Sunday Prime Time

Michael Apted’s compelling BBC documentary, “From 7 to 28 Up,” highlights tonight’s television schedule. The 90-minute film, airing at 9 on Channel 28, documents the changes in the lives of a group of British youngsters over the course of two decades by splicing together interviews with children and young adults when they were 7, 14, 21 and 28 years old.

On Sunday, Robert Urich, Ben Cross, Dirty Harry and the “Masterpiece Theatre” gang will battle it out for the bulk of the prime-time audience.

Urich stars as an aging ex-football star who falls for his son’s girlfriend in “The Comeback,” 9 p.m. on Channels 2 and 8.

NBC counters at 9 p.m. (4)(36)(39) with the first episode of a two-part “Twist of Fate,” a World War II story featuring Cross and Victoria Hamel.

Clint Eastwood will shoot up the screen on ABC (7)(3)(10)(39) at 9 p.m. as Dirty Harry Callahan in his 1983 movie “Sudden Impact.”

And “Masterpiece Theatre” serves up “A Wreath of Roses,” with Joanna McCallum and Trevor Eve in a story of love and death, 8 p.m. (50)(24) and 9 p.m. (28)(15).
