Extremely odd story of a 35-year old man who, for reasons no doctor can figure out, loses all of his memory. He remembers how to walk and talk and swim and sign his name — though the signature is so bad and he can’t make it out to learn what he is called. Turns out he *used* to be a fairly obnoxious stock broker who retired at 30 to “take up photography.” Now he has an adult mind, but the eyes and ears of a precocious child. “I just discovered this terrific band — The Rolling Stones!” Old friends who have a lifetime of experiences with him are strangers, now he’s making new friends. Doctors think his memory will come back eventually. What will happen when the old identity starts interacting with the new one? The movie discusses fascinating themes of heavy philosophy, but the story doesn’t really go anywhere after the initial premise. Filmmaker Rupert Murray does a good job masking this with unusually arty photography for a documentary. Very watchable.
