The Lawrence Batley Theatre will play host to spooky characters and thrilling shows for its fourth annual Halloween Happening.
A re-imagining of Faust legend The Devil Without will take place on the Main Stage, combining magic, storytelling and infrasound and taking inspiration from Neil Gaiman and Alan Moore.
You may also bump into Miss Havisham in the theatre's corridors, and learn the secrets of her broken heart, while High Priestess will tell cautionary tales from the Caribbean in Duppy Stories.
Michael Jackson fans can learn the Thriller dance in a fun workshop with LBT choreographer Pauline Mayers.
And if you're feeling brave, take a seat in the Electric Chair or let special effects makeup artist Douglas Thompson 'mutilate' you with some wickedly wonderful wounds and scars.
Take a peek inside murderous Mr Punch's Cabinet of Curiosity, filled with strange objects and their stranger backstories, from the darkest corners of the globe.
And the party will continue with live music and Big Band swing from Les Vegas and the International Playboys of Rhythm.
For some Halloween laughs, check out Short Sighted Cinema's Die Laughing , a comedy-horror film programme full of adult humour, guts and gore.
A company of spooky spirits will roam the LBT corridors and spirits, and you can join Sweeney Todd for a special pie and pea supper.
And there are more hair-raising happenings to be revealed...
The Halloween Happening runs from 7pm-late, and the dress code is fancy dress.
Tickets cost £15/ Early Bird £13, including a pie and pea supper.
