It's difficult to think of just one. Scorsese delivered some fine work in the 80's such as 'Raging Bull', 'The King of Comedy' and 'After Hours'. It was a great decade for action films such as 'Die Hard', 'Lethal Weapon' and 'Midnight Run'. Then there's 'Mona Lisa', 'The Long Good Friday'. 'Diner', 'Amadeus', 'The Untouchables'....

Great Scott... Marty... 1.21 Gigawatts... Flux Capacator... Dolorian time machine... Back to the Future is "THE" film of the 80's, with the exception of Raging Bull, but for cooleness, Back to the Future definately wins
