Traditionally a sneak peek at next year's awards season, the 2015 London Film Festival begins on 7 October, and we've rounded up the films, shorts and documentaries exploring technology and other geeky pursuits.
Steve Jobs, cyberstalking, Evel Knievel and Star Wars are just some of the subjects of films in LFF 2015.
To kick off our gallery, stars from a galaxy far, far away discuss how their lives changed when they appeared in even the tiniest "Star Wars" roles in the documentary "Elstree 1976", named after the London film studio where the first movie was shot.
"The American Sessions" sees musical luminaries such as Elton John, Nas and Willie Nelson record using a recreated Western Electric lathe, the pulley-operated analogue device that pioneered recorded music.
Documentary "Hot Sugar’s Cold World" follows musician Nick Koenig as he shares his musical techniques and hangs out with friends including physicist Neil deGrasse Tyson.
OK, this one doesn't have anything to do with technology or geeky stuff. But it's called "Bone Tomahawk" and it's got Kurt Russell's mighty moustache in it, and that's good enough for us.
