Peterloo is a 2018 British historical drama, directed and written by Mike Leigh, based on the Peterloo Massacre of 1819. The film was selected to be screened in the main competition section of the 75th Venice International Film Festival. The film received its UK premiere on 17 October 2018, as part of the BFI London Film Festival, in Manchester. The screening marks the first time the festival has held a premiere outside London. Leigh said he was delighted that Peterloo would be premiered "where it happened."
