Time is a foundational element of cinema, as the medium captures and manipulates, plays and re-plays, deconstructs and reconstructs, presents and re-presents time. An eternity can be reduced to an instant and an instant extended to an eternity. David Lowery’s A Ghost Story explores time and our fluctuating perception of it, and is also a mournful and moving story. How does our perception of time change when we cannot adjust to a world changed by loss? Grief keeps us locked in the moment of loss, the famous five stages – denial, anger, bargaining, depression, acceptance – related to the moment of someone being gone, rather than the revised state of the world in which they are gone. Lowery explores these concepts with exquisite focus and restraint, using the specific possibilities of cinema to portray the experiences of grief, time and timelessness with precision, grace and humanity. We see the film’s central characters C (Casey Affleck) and M (Rooney Mara) experience events in their lives that are remarkable in their unremarkableness: a discussion about moving house; investigating sounds in the night; listening to a song composed by C. Following the death of C, and his haunting of their home under a white sheet with eye holes, scenes are played out with varying presentations of time. What could be days, months or years pass in seconds, while in one bravura sequence, M eats an entire pie in almost a single take. This scene is almost unbearably uncomfortable, conveying the non-time that M and the watching ghost experience, completely separate yet unable to disconnect. The long take is the film’s most used and effective device, as it not only prolongs uncomfortable sequences, but also impacts on the viewer’s expectations of cinema. Various shots continue far past the point at which we expect a cut, highlighting our engagement with cinema and with time itself. Much like the ghost, we constantly wait for things to move on, and when they do not we may be discomfited but then again we may embrace the film’s conceit of reassessing our engagement and experience of time. A Ghost Story invites such responses but never provides answers, offering only the most tantalizing questions as an experience that is both frustrating and compelling.
