The story was inspired, according to Knoll, by World War II adventure films that had energized Lucas, pictures like The Dam Busters (1955) and The Guns of Navarone (1961).
Star Wars took direct inspiration from the behind-enemy-lines "men on a mission" pictures of his youth, like 1955’s The Dam Busters and 1961’s The Guns of Navarone.
While these are all enjoyable treats, what makes Rogue One such a rewarding watch is that Edwards has given us a romp of a war movie, cut in the mould of 633 Squadron and The Dam Busters .
