Halloween is almost here. Musician and film director Rob Zombie hosts AMC’s traditional Fearfest, a seven-night countdown to the holiday, featuring more than 175 hours of scary movies, culminating in Zombie’s own “Evil 8 Countdown” on Halloween, an all-day marathon of chilling thrillers and monster movies.

Tonight’s fearful features include the 1978 slasher classic “Halloween” (7 p.m.), directed by John Carpenter. “Halloween 4: The Return of Michael Myers” (9 p.m.) follows and is in turn followed by “Halloween 5” (11 p.m.).

The Family Channel is already on its sixth night of scary shenanigans, offering the 1993 remake sequel “Addams Family Values” (7 p.m.), starring Anjelica Huston, Raul Julia, Christina Ricci and Christopher Lloyd.

The Travel Channel offers three consecutive helpings of “Ghost Adventures” (7 p.m., 8 p.m. and 9 p.m.). Eddie Murphy stars in the 2003 theme park-inspired feature “The Haunted Mansion” (8 p.m., Disney), and, of course, Jennifer Love Hewitt stars on “Ghost Whisperer” (7 p.m., CBS), where every day is Halloween. On tonight’s “Whisperer,” Melinda strives to stop a honeymoon haunting.

Not all scary programming has to involve the supernatural. “World’s Scariest Police Chases” (7 p.m., Tru TV) speaks for itself. And so do two consecutive episodes of “Women Behind Bars” (8 p.m. and 9 p.m., WE). The night’s most terrifying scenes may belong to a repeat helping of the second-season premiere of “Celebrity Rehab with Dr. Drew” (7:30 p.m., VH1). Few shows do a more harrowing job of showing the terrors of Hollywood’s party culture. It should scare some viewers straight.

¢ Leave it to a German-born supermodel to learn the most valuable lesson from Mark Twain’s “Tom Sawyer”: If you make a task (like painting a fence) look fun and hip, then other people will do all of the work for you.

Measured by memorable scenes or words spoken, Heidi Klum, the subject of tonight’s “True Hollywood Story” (8 p.m., E!), hardly seems to be the star of “Project Runway.” She exchanges a few pleasantries with the talent, offers a quip or two to the judges and dismisses each week’s loser with a breathy “auf Wiedersehen.”

But it takes a certain self-confidence to step back and turn other people into stars. “Runway” participants Tim Gunn and Michael Kors appear on this expose and have nothing but nice things to say.

“True” reveals that Klum owes her start to a TV contest. In 1992, 18-year-old Klum was chosen from thousands of faces to be crowned model of the year on a popular German TV show.
