George Clooney

Played Frank Walker, a disillusioned former boy-genius exiled from a hidden city of the future — a rare Clooney role built around weary disappointment rather than easy charm. Already an Academy Award winner and one of Hollywood's most bankable leading men, he took on a role deliberately written against his usual effortlessly charismatic screen persona. The film marked one of his more overtly science fiction-oriented roles in a career otherwise dominated by drama and comedy.
