It may be snowing in Battersea, but things are definitely hotting up for Halloween

Sport

It may lack altitude and Glühwein, but 2010's London's Relentless Freeze Festival does have a mountain of world-leading freestyle ski and snowboard athletes competing over a series of "jump" events, held on and around a 32-metre-high, 100-metre-long ski ramp (with real snow) in front of Battersea Power Station. Don't forget the cowbell. Friday to Sunday, thefreezefestival.com

Film

Penned and illustrated by Finnish national treasure Tove Jansson, the whimsical adventures of the troll-like Moomins have spanned nine books, myriad comic strips and a series of animations. And now they're COMING RIGHT AT YOU!!! In 3D, with a big-screen, stop-motion animation outing. Moomins and the Comet Chase premieres at the London Children's Film Festival on Saturday. If you can't deal with the histrionics of 3D on a weekend, a more laid-back option is available at Bury Art Gallery, where an exhibition of Jansson's original artwork is on display until early next year. The film festival (lcff.org. uk) runs until 7 November; Bury Art Gallery, tel: 0161 253 5878

Fashion

Since Antony Price styled Roxy Music, the fashion and pop industries have become inseparable. The Mercury Award-winning The xx are our current sartorial darlings with their retro-grunge and deeply dark aesthetic – and denim gurus Lee are supporting the band with a limited-edition Midnight Rider range, featuring pieces emblazoned with the band's signature white crosses. Perfect for rocking around town. Available from November; jacket, £135, lee-store.com

Harriet Walker

Music

Yet more rocking around town: London's music venues have been dropping like flies over the past few years, but the owners of Oxford Street's 100 Club, the birthplace of punk, are not going to go down without a ruddy great din. On 1 December, bluesman Stephen Dale Petit is organising a Guitar Heroes benefit gig, when he will be joined by legendary axe-wielders from Ronnie Wood to his Stones predecessor Mick Taylor as they do their bit to clear the club's £500,000 debt. Tickets are £35 in advance, wegottickets.com. All profits go to the Save The 100 Club campaign

Food

If you're spending Halloween dressed asa ghost in a single sheet, it's bound to feel a bit chilli. No, it's not a typo: next Sunday, the Anderson Hotel in Fortrose, near Inverness, hosts its third annual chilli-off, at 6pm. An entry fee of £3 towards the British Heart Foundation Scotland opens up a world of pain, with chillis increasing in intensity with each round. Be warned: "We've finally found an English source for the legendary Bhut Jolokia pepper," they say. theanderson.co.uk/splashwon.htm

Theatre

Continuing the Halloween theme, a dose of the heebee-jeebies is on the menu at west London's Chelsea Theatre, where, as part of its Sacred season, waxwork whiz Anthony Bennett is teaming up with Olivier-award winning performance artist Marissa Carnesky and New York artists Rasp Thorne for 'The Quickening of the Wax', a ghoulish show performed amid waxwork effigies, in an exploration of the cult of the supernatural. Thursday to Saturday, chelseatheatre.co.uk
