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.

There is no electricity, no water and no communications with the outside world apart from a 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.

[1] 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.
