Grigsby’s film [pictured] is one of three documentaries screening throughout September as part of the London-based year-round festival.

Following a summer break, London’s DocHouse is returning with three award-winning international documentaries.

Their September programme kicks off with Michael Grigsby’s We Went To War, which sees him explore the long-term effects of war, on Sept 6 at the Riverside Studios. Grigsby will be in attendance at the screening of his film, where his 1970 TV documentary I Was A Soldier will also screen, for an extended Q&A.

Trisha Ziff’s The Mexican Suitcase, which centres around the discovery of three boxes of photographs in Mexico City in 2007, screens on Sept 13 at The Lexi. Fredrik Gertten’s Big Boys Gone Bananas!*, about Gertten’s legal battle against a multi-national corporation, rounds off the programme on Sept 18 at the Prince Charles Cinema with Gertten and communications advisor Sven Hughes on hand for a post-screening Q&A.

DocHouse is partnered with London cinemas The Lexi Cinema, Rich Mix, Prince Charles Cinema and Riverside Studios, with The Bertha Foundation as its sponsor.
