'Blade Runner' -- Harrison Ford vs. Dustin Hoffman
In his memoir, "Blade Runner" producer Michael Deeley talked about the search for android hunter Rick Deckard. Dustin Hoffman was set to star and had "buried himself in this character," according to Deeley. But over weeks of script revisions, the filmmakers began to feel that Hoffman's vision had moved farther away from theirs. They screened production footage of "Raiders of the Last Ark," and Harrison Ford won them over.
