OK, now, don't be scared: Some networks have been celebrating Halloween already, but here comes the real trick-or-treat deal.
The new week begins on the eve of the annual visits from little candy-seeking goblins and witches -- along with the occasional Spider-Man and Disney princess -- and television is well aware of the occasion. Between movies, specials and appropriate series episodes, the home screen will have viewers well covered today and Monday.
Here's a look at some of the horrifying highlights.
ABC: Tonight's "Desperate Housewives" goes for the macabre with a story about moving the body of Gaby's slain stepfather with Tony Plana, who played the now-deceased man, directing the episode. And "Dancing With the Stars" hadn't confirmed its plans for Monday at this writing, but with costuming a big element of that show anyway, it would be surprising if at least one duo didn't fold in a Halloween salute.
CBS: The "CSI: Miami" team faces an eerie challenge today, courtesy of a maid who appears to have died from a vampire's neck bites. Monday, Katie Holmes pays a visit to "How I Met Your Mother" as the so-called "Slutty Pumpkin," then "Mike & Molly" attend a Halloween party, and Robert Englund ("A Nightmare on Elm Street") appears in a "Hawaii Five-0" case about a Hawaiian burial site.
NBC: There's no question "The Sing-Off" will be in the spirit of the evening Monday, since the set will be done up as a cemetery, and the seven remaining a cappella groups will perform tunes on the order of "Ghostbusters" and "Werewolves of London."
Fox: What would a season of "The Simpsons" be without another "Treehouse of Horrors" episode? Volume XXII airs tonight, with Aron Ralston -- the climber whose survival story fueled the movie "127 Hours" -- voicing his cartoon likeness to help Homer out of a similar plight.
ABC Family: "America's Funniest Home Videos" repeats on both today and Monday have a Halloween theme, but mainly, the last two days of the network's "13 Nights of Halloween" festival involve movies "The Addams Family," "Practical Magic" and "Van Helsing" today, and "Casper" and "Hocus Pocus" Monday.
AMC: The series "The Walking Dead" provides chills on a weekly basis, but coming the night before Halloween, today's new episode -- set largely in a school that just happens to be filled with the undead -- should have special relevance. And both today and Monday, the roster of movies boasts several of the "Halloween" thrillers, including the 1978 original that put star Jamie Lee Curtis and director John Carpenter on the map.
FX: The first "Twilight" movie is the centerpiece of the network's Halloween weekend schedule today, but also worth noting are two efforts from spooky specialist filmmaker M. Night Shyamalan, "The Sixth Sense" with Bruce Willis and "The Happening" with Mark Wahlberg and Zooey Deschanel.
Hallmark Channel: A "Good Witch" festival of Catherine Bell-starring TV movies is on tap today, including the newest one, "The Good Witch's Family." And Monday offers Halloween-oriented repeats of "The Waltons," "Little House on the Prairie" and "Frasier."
Spike TV: Today, the underrated movie melodrama "The Unborn" with Odette Yustman will be followed by Sara Paxton ("Shark Night 3D") in the 2009 remake of "The Last House on the Left."
Syfy: "Ghost Hunters Halloween Live" pretty much says it all, as Monday's annual special takes investigators from both "Ghost Hunters" and "Ghost Hunters International" to and through a now-abandoned Pennsylvania asylum.
Turner Classic Movies: Always a Halloween haven at this time of year, the channel gives chillers "starring" Frankenstein, Dracula and the Mummy a television home Monday along with the original, still-hair-raising version of "Night of the Living Dead."
