If you saw the 2014 indie thriller Blue Ruin, director Jeremy Saulnier might already be on your radar. But his new film Green Room is seriously going to put him on the map. It’s one of those movies that it’s kind of best not to know anything abut going in, but essentially it’s about an Oregon punk band who take on a show at the last minute. It turns out the venue is full of neo-Nazi skinheads, and things get very bad, and very violent, very quickly. Plus it features the usually lovable Patrick Stewart as a terrifying white supremacist leader.

The film drops in UK cinemas on May 13, and we’ve got the exclusive of the UK poster here, to give you a taste.
