Brawl in Cell Block 99 (2017, dir. S. Craig Zahler)

A mechanic turned drug mule has to battle the prison system to save his pregnant wife from the dealers he owes. Slow-paced but inexorable, this crime drama/horror mash-up isn’t for everyone, but is both brilliant and brutal if you can go with it.

Infinity Chamber [AKA Somnio] (2016, dir. Travis Molloy)

A man wakes up in a high-tech cell, with only a voice-enabled robot camera for company. Neat one-room SF thriller with shades of Moon, Cube and 2001: A Space Odyssey. As ever, the puzzle is the thing; this just about earns its resolution.

How I Spent My Summer Vacation (AKA Get The Gringo) (2012, dir. Adrian Grunberg)

A nameless bankrobber has to work his way out of a Mexican prison while evading the mob. Splendidly stylised black comedy action thriller, making best use of its star’s talents, and exploiting every opportunity to indulge itself in grim jokey chuckles.
