What does the 2016 film Arrival tell us about time, and our relationship to it? If you knew your future and could choose, would you live it exactly as it is to unfold? Does foreknowledge of the future course of our lives imply that there is no free will? Would it be wrong to inform loved ones of the tragedies you see for them? Would it be wrong to enter into relationships that you know will end in tragedy? These and other questions are explored in this film.
