The basic plot of The Father mirrors the all-too-common trajectory people with dementia follow: first they deny any problems; then they progressively need more in-home assistance; and then they require institutionalization. This scenario, however, gets obscured when watching the film’s main character—the father—wrestle with quotidian activities and familiar faces. The viewers wrestle with him, and become just as confused and rattled. Florian Zeller, the screenwriter and director, admits he wants viewers feeling what people with dementia feel. He succeeds in the movie as he succeeded in the Broadway play version preceding it.

The father, Anthony, lived in his London flat with help from hired caregivers and his daughter, Anne, who lived nearby. After Anthony banished several caregivers on grounds they were unnecessary, Anne moves him into her flat, and when he’s too much for her there, she moves him to a nursing home. We’re never quite sure, though. Zeller makes the two flats and the nursing home look almost identical. He changes Anne’s story at different times: she’s still married after ten years; she’s been divorced for five years; she’s relocating to Paris with a lover; she was never relocating to Paris; she relocated to Paris. Anne appears as a different person on occasion and the husband she may or may never had appears as different people. Zeller overlays these confusing surroundings and events by jumping forward and backward in time, and repeating some scenes with slight variations. Eventually, Anthony says, “strange things are going on around us.” Viewers will feel the same, and that’s the point.

The movie ends as Anthony awakes in his nursing home room. Just as we are lured into thinking we have returned to the common dementia trajectory at its end, we see his nurse is the person who had appeared as Anne before, and his room looks like the bedrooms in both his own and Anne’s flats. We wonder.
