Infinitum: Subject Unknown
2021, English. Directed by Matthew Butler-Hart.
Destined to repeat forever... The test is to find a way out.
Jane is the subject of a twisted science experiment where she is placed in a parallel world and is forced to find a way to either alter her reality or be stuck in a time-loop, destined to repeat the same test over and over again, with no memory of her doing it before. But with each 'reset' she starts to retain fragments of memory. With clues pointing to the mysterious Wytness Quantum Research Centre, she tries to find a way out. (The film was shot entirely on an iPhone during the UK’s first lockdown.)
