Robert Zemeckis's 1985 comedy sends Marty McFly thirty years into his parents' past, where undoing his own accidental sabotage of their romance becomes a race against his own existence. Recast five weeks into shooting, rewritten forty times before a studio would touch it, it turned into the biggest hit of its year on a modest budget, and the mechanics still hold.
Miloš Forman's adaptation of Ken Kesey's novel puts Jack Nicholson's disruptive new patient against Louise Fletcher's controlled head nurse inside the Oregon State Hospital, an operating psychiatric facility used as the actual set. Made for $3 million after a development history stretching back to 1962, it became one of only three films to sweep the top five Academy Awards, and it still plays as a study of institutional control rather than a simple underdog story.
Robert Zemeckis's 1988 noir comedy places a toon-hating private eye in an alternate 1947 Hollywood where cartoon characters live alongside humans, tasking him with clearing Roger Rabbit of a murder. Produced by Disney and Amblin with animation supervised by Richard Williams, it required Disney to negotiate cameo rights with Warner Bros. and other studios, and became the second-highest-grossing film of 1988.
