Ice Station Zebra (1968, dir. John Sturges)

A US submarine is tasked with a rescue mission to the Arctic, in part as cover for a covert operation. Oddly talky Cold War drama, through with solid technical credits and some fun performances, not least from McGoohan. The relative lack of action is compensated for in part by some great model work and an anti-militaristic angle.

Crimson Tide (1995, dir. Tony Scott)

A submarine captain and his new second-in-command clash during a military crisis. Excellent testosterone-fuelled drama, making full claustrophobic use of naval service underwater tropes. Superior technical credits and a rousing score supplement the crew of capable character actors.

Kursk: The Last Mission [AKA The Command; AKA Kursk] (2018, dir. Thomas Vinterberg)

A sombre retelling of the 2000 Kursk submarine disaster. Okay drama-documentary that takes some liberties with the actual timeline, and which struggles to make the inevitable dramatic, despite good performances. The usual points made.

Hunter Killer (2018, dir. Donovan Marsh)

A US submarine captain attempts to prevent a rogue minister-led coup in Russia. Old-fashioned military thriller aping the likes of Tom Clancy. Not bad while its on, though there’s not one surprise; a game cast of character actors play the material straight.
