Biography (8 p.m., A&E) continues "Charlie's Angels" week with a profile of Farrah Fawcett.

Specials

For the first time ever, New York's Greenwich Village Halloween Parade (7 p.m., USA, Sci-Fi Channel) is televised nationally. Susan Sarandon, Kathy Griffin and Tommy Davidson host. If it's scary movies you want this Halloween, there's a marathon of 'em on Monsterfest (all day, American Movie Classics). A repeat of Inside the Actors Studio (8 p.m. EDT/9 p.m. PDT, Bravo) features a scary chat with Anthony Hopkins. Then, watch the master at work in Silence of the Lambs (9 p.m., Lifetime). What would Halloween be without Night of the Living Dead (8 p.m., Independent Film Channel)? And for a special spooky treat, there's the new cable movie Dark Prince: The True Story of Dracula (9 p.m., USA), a gory retelling of the legend of Vlad, starring Rudolf Martin, who played Dracula in a lighter vein (sorry) on this season's "Buffy the Vampire Slayer" opener.
