When Artificial Intelligence Meets a Failing Mind

Every time Marjorie recounts a story to her husband Walter, his refrain isn't, "I remember that now." Instead it's, "I'll remember that now." That shift from present to future tense is pivotal because he cannot recall those moments from their marriage – flags in the park, the death of their son, what bad film was playing when he proposed – because he was never there. Walter is Walter Prime, a sophisticated AI serving as Marjorie's companion. The real Walter (Jon Hamm) has been dead for decades, while 86-year-old Marjorie (Five Easy Pieces' Lois Smith) is going senile.
