Containment is a 2015 British thriller film written by David Lemon, directed by Neil Mcenery-West, produced by Casey Herbert, Pete Smyth and Christine Hartland; and starring Lee Ross, Sheila Reid, Louise Brealey, Pippa Nixon, Andrew Leung, William Postlethwaite and Gabriel Senior. The film's executive producer is Simon Sole.
The film is set in a 1970s era council block in Weston, Southampton set in the present-day United Kingdom. Mark, an artist, wakes to find that he has been sealed into his flat with no way out. There is no electricity, no water and no communications with the outside world apart from a scary voice over the intercom, repeating the phrase, "please remain calm, the situation is under control". Strange figures in Hazmat suits patrol the grounds outside and set up a military tent. Mark's neighbour, Sergei, breaks down the wall between their flats in order to discover why they have been sealed in and try to find a way to escape. Along the way, they team up with their fellow residents, Enid, Sally and Aiden.
Mcenery-West began working on the film in 2008 as he had always been attracted to contained thrillers and wanted to do a modern urban version of something like Lord of the Flies. Mcenery-West's original idea was focussed on the concept of just one character trapped alone in his apartment but Lemon expanded the story to include a diverse group of characters in order to avoid what Lemon felt was "one man on a stage".
The film commenced filming on location in Weston Tower Blocks, Southampton in April 2014. The blocks remained occupied during filming with many of the location's real residents acting as extras in the film. Lemon had a cameo as one of the mysterious figures in a Hazmat suit.
In May 2015, Vision Films acquired the worldwide rights to the film and the film premiered in July 2015 as part of the East End Film Festival and will preview at the Henley Fringe Festival ahead of its UK theatrical release in September 2015
