FRIDAY Back to the Future (NBC, 8-11 p.m.): It's the 1985 film comedy smash with the tantalizing plot about the high school student who travels back 30 years and meets his parents as teenagers. Yes, it's aired before, but this three-hour special hosted by Leslie Nielsen also offers clips from the yet-to-be-released sequel, ``Back to the Future 2.'' SUNDAY The Fatal Attraction of Adolf Hitler (A&E cable network, 8-9 p.m.): The BBC - along withAustralian and New Zealand broadcasting groups - joined A&E in this two-part documentary attempting yet again to account for how it all could actually have happened, beginning with Hitler's birth 100 years ago and including personal testimony from his intimates. (Part 2: Nov. 26). Masterpiece Theatre (PBS, 9-10 p.m.): Premi`ere of a four-part version of ``A Tale of Two Cities,'' the Dickens classic set against the French Revolution. Lots of deservedly familiar names in this one - like John Mills as Mr. Lorry, Jean-Pierre Aumont as Dr. Manette, and James Wilby as Sidney Carton.
MONDAY P.O.V. (PBS, 10-11:30 p.m.): The letters stand for ``point of view'' - TV-speak for the kind of advocacy filmmalking seen in this tough, explicit, but potentially constructive documentary about a big social problem: homeless teenage girls.
