The big event is probably a 40th anniversary screening of The Harder They Come followed by a DJ set from Don Letts, so you can party on into Sunday morning. Or how about another 40th anniversary, this time celebrating The Wicker Man with Noise of Art's Disco Inferno: electronica music, cinema, and spoken word from actor Nathaniel Parker.
If you're a skater take your board down on Sunday for an afternoon of skating to prime beats, followed by skate film screenings and a performance by UK beatbox champion Reeps One. A more sedate Sunday option might be a screening of London to Brighton plus Q&A with actor Johnny Harris.
There's food from The StockMKT, or take your own grub to roast at the Latin Sunset BBQ. You can take a tour of the subway murals, go on a treasure hunt, do some guerilla gardening or test your E&C knowledge in a pub quiz. Film screenings and the closing party with Smoke Fairies cost £5, or you can buy a £10 pass that gets you into everything, but most events are free.
Elefest takes place 4-6 October at various venues around Elephant and Castle. See the Elefest website for more information and to book.
