They’re creepy and they’re kooky, mysterious and spooky, they’re all together ooky, the Herald Halloween arts preview! Blood, bats, and pets dressed as bats, what more do want from a Halloween activity?

Roger Corman: King of Cult, now through Oct. 24, Brattle Theater

The producer/director didn’t invent schlock horror, he just perfected it, re-perfected it, and then re-re-perfected it. While Corman has plenty of directorial credits to his name, he may be best known as giving a couple of generations of filmmakers their first chance to helm a feature — see Francis Ford Coppola and Penelope Spheeris. To get at his aesthetic, just take a look at some of the titles the Brattle is showing: “Chopping Mall,” “Galaxy of Terror,” “The Slumber Party Massacre,” and “Slumber Party Massacre II.” brattlefilm.org

“Simon Says,” now through Oct. 27, Larcom Theater, Beverly

Do we embrace love or retreat into fear? That simple question sits at the center of Mat Schaffer’s play. Around the question orbit other ideas, stranger ideas: faith and fate, past lives and psychics, the belief that there are no accidents. A perfect play for the season of spirits. thelarcom.org

“The Rocky Horror Picture Show” with Nell Campbell, Oct. 25, Emerson Colonial Theatre

With a bit of a mind flip… You’re into a time slip… And nothing can ever be the same. Let’s do the time warp with Nell Campbell again. The original Columbia from the film, Campbell stops by Boston for a screening with a live shadow cast and all the audience participation you know, love and dread.  emersoncolonialtheatre.com

Wolf’s Pumpkin Bash: An Unexpected Mardi Gras(ish) Jamboree, Oct. 30, Lizard Lounge, Cambridge

Who do that voodoo you love so? Why the Legendary Vudu Krewe, of course. The local, well, legends, put on a New Orleans rhythm and blues party like no others. As they say, “It’ll be the day before the day before the day before the Day of the Dead, so dress opportunistically. You know what to do.” lizardloungeclub.com

Skalloween. Oct. 31, The Rockwell, Somerville

Skank your way through All Hallow’s Eve with the oddest set of bands covering the oddest set of bands. How odd (and wonderful)? Skaleton Crew does Skank Against The Machine, Battlemode as Limp Bizkit, Pink Slip is Less Than Jake, the New Limits become the Interrupters, and Please Excuse My Enemies does Streetlight Manifesto. therockwell.org

Werewolves, Witches, and Zombies on the Criterion Channel, online

All October, the Criterion Channel streams collections of horror (and horror adjacent) films. There’s a package of movies that chronicles make-up and special effects before CGI that runs from 1931’s “Frankenstein” to 1968’s “Night of the Living Dead” and 1981’s “An American Werewolf in London” through 1986’s “The Fly.” A coven of witches cast creepy spells from the silent era to the new millennium including “Rosemary’s Baby,” “The Crucible,” and “Sabrina the Teenage Witch.” A new wave of Japanese films scared the heck out of a whole generation; join the generation with modern classics such as 1998’s “Ring” and 2002’s “Ju-On: The Grudge.” criterion.com

If it’s scary, it’s on the Criterion Channel this month. Check out creepy flicks like “Spider Baby.” (Photo courtesy Criterion Channel)
