Peterloo is a 2018 British historical drama, written and directed 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, at HOME in Manchester. The screening marked the first time that the festival had held a premiere outside London. Leigh said he was delighted that Peterloo would be premiered "where it happened".
