By tracing what happened next, the film leads us to the question: are we in the age of Alzheimer’s cure? Holly Richardson

Movie selection

Outland (Peter Hyams, 1981), 21:00, 5 Action

Basically High Noon in Space, Peter Hyams’ 1981 sci-fi thriller is one of the best films to come out since the ground-breaking Alien (that film’s composer, Jerry Goldsmith, contributes a similarly unnerving score here). Sean Connery is the last good guy standing as the federal marshal of a mining colony on Jupiter’s moon Io. When he gets in the way of a (company-sanctioned) illegal trade in performance-enhancing amphetamines, assassins are sent after him. Dirty and captivating. Simon Wardell
