Watch Runtime (2019) Official Trailer

Conor Bateman has sliced clips from (mainly American) horror films in which a cinema audience is slain schlockily in a theatre – an overlooked, self-reflexive trope across the genre. In each sequence, the screen is masked out to reveal the prior sequence: each audience is successively watching the killings that we, the actual audience, have just seen. The onscreen audience never leaves the theatre – there’s nowhere else in this world beyond the cinema, and the scenes of entrapment and containment play out in similarly-framed spaces of chaos (what if what we watched onscreen leaked out?). Without a scrap of ideology-addled earnestness, the tone moves from playful to inevitable. Like a game, it all loops together in an oddly fun, self-sustaining spiral of dramatic irony.
