Green Room is a horror film starring Patrick Stewart and Anton Yelchin, making it something of a Trekgasm. Make that a Borgasm.

“Make it ϟϟo.”

Jeremy Saulnier’s new movie follows a punk band who end up playing at a neo-Nazi bar, resulting in a bloodbath of punk-rock proportions and the most intense 90 minutes since my last delay on Southern rail.

Saulnier keeps the tension as tight as drum skins, and rattles your nerves like snare wires. Like his last movie Blue Ruin (he must like colour-based titles), the film effectively combines black comedy with an airtight atmosphere and extreme violence. Very extreme violence.

There are killer performances from both Yelchin and Stewart, who lends gravitas to proceedings as the neo-Nazi leader (or captain, if you will). Also impressive are Imogen Poots, Macon Blair and Alia Shawkat from Arrested Development. Expect Maeby Fünke to join a punk band in season 5. 

Where last month’s 10 Cloverfield Lane offered a similar trapped-in-a-room scenario, we knew exactly where it was going (thanks to the title). Here, we never know what’s around the corner; only that it won’t be pretty.

With Green Room, Saulnier delivers another small explosion of a movie. This, as they say, is hardcore.
