Nightshooters (2018).
A group of guerrilla filmmakers are shooting in a building due for demolition without a film permit. Then they witness a brutal murder, and then they are witnessed witnessing the brutal murder.
The rest is pretty darn tasty. The stunt work and fight scenes are great. The characters build. There is a strong female lead. There is a dick who doesn’t get redemption. The movie was actually shot over just 17 days in a real building that was demolished at the end. The tea urn is the tea urn.
This is, rather surprisingly, really quite good. I could watch this happily again.
