The Peacemaker: LA. Gang Wars (10-11 p.m. Thursday. A&E.) - A new reality series follows a gang mediator who works the nighttime streets of South Central Los Angeles, trying to keep the gunfire down to a dull roar. Produced by Law & Order: SVU's Ice-T, a former gangbanger himself.
Miracle on 34th Street (10:15 p.m. Friday. AMC.) - This classic 1947 film starring Natalie Wood as a little girl who doesn't believe in Santa Claus and Edmund Gwenn as a Macy's Santa who's certain he's the real thing is bitingly funny as well as far more profound than its cute plot set-up suggests. It's really a meditation on the nature of faith. Or as Wood's mom tells her: "Faith is believing when common sense tells you not to." This screening is part of a four-day AMC marathon that continues through Monday;
every night at 8, the network will screen the colorized version for committed modernists, followed at 10:15 by the original black and white.
