Where Eagles Dare is a 1968 action adventure war film directed by Brian G. Hutton and starring Richard Burton, Clint Eastwood and Mary Ure. Set during World War II, it follows a Special Operations Executive team charged with saving a captured American General from the fictional Schloß Adler fortress, except the mission turns out not to be as it seems. It was filmed in Panavision using the Metrocolor process, and was distributed by Metro-Goldwyn-Mayer. Alistair MacLean wrote the screenplay, his first, at the same time that he wrote the novel of the same name. Both became commercial successes.
