Dune (1984)
Seen four times, dated but good for its time. Visuals are still strange in ways no modern adaptation has matche.
Sting fronted The Police and has one of the most successful solo careers in popular music, and the acting has been intermittent. Dune gives him Feyd-Rautha in a costume that has outlived the film’s reputation, and Quadrophenia and Brimstone and Treacle gave him earlier work. He has said he takes screen roles mainly out of curiosity.
