240 films. 72 countries. 16 cinemas. 12 days. One festival: The BFI London Film Festival. Now in its 59th year, it is the jewel in the BFI's crown. Both the BFI and the BFI London Film Festival are what they say they are: British institutes. Here's your chance to get involved. For this event, catch a screening of Der Nachtmahr, a work by the German visual artist and director Akiz. It's summer in Berlin: friends are coming together to party and celebrate a break from school. 17-year-old Tina Peterson, however, is having her fun disrupted by a grotesque, otherworldly homunculus. As her mental state deteriorates, this surreal, ambitious work pushes the viewer into a zone of unsettlement. This is a good thing: challenging in all the best ways, you won't forget this viewing experience. Over 15s only. Runtime: 98 minutes.
