A drama about Wikileaks founder Julian Assange and Japan’s version of Life in a Day have been added to the 56th BFI London Film Festival.

The European premiere of Underground, directed by Robert Connolly (Balibo), will be held at the BFI Southbank on Oct 11.

Based on the book by Suelette Dreyfus, the drama covers Assange’s early years as a teenage hacker in Melbourne.

Japan in a Day will screen on Oct 20 at the BFI Southbank to coincide with the world premiere at the Tokyo International Film Festival.

Based on the documentary format of Kevin MacDonald’s Life in a Day, in which people from around the world submitted clips of their lives from one specific day, it centres on 11 March 2012 – the anniversary of the Great East Japan Earthquake.

Scott Free Productions and Fuji TV collaborated on the project, in which Japanese citizens were invited to pick up a camera and capture something about their day. Japanese director Gaku Narita and British director Philip Martin, alongside editor Kristina Hetherington, fashioned the documentary from more than 8,000 films uploaded onto YouTube.

It will be followed by a Q&A with some of the film’s contributors live from Tokyo.
