Edge of Eternity

Although Siegel has expressed his dislike of CinemaScope, exploiting the magnificent scenery of the Grand Canyon gave him ample reason to use the widescreen process for the first time. In the event, the aerial footage and a hair-raising climactic set-to on a dangling cable car are the movie's strongest suit, since the routine material cast Wilde as the unassuming local sheriff with a troubled past, investigating the murder of a 'John Doe' in the canyon while romancing mine-owner's daughter Shaw. If Wilde's performance seems particularly stolid, it's worth noting that he was recovering from a painful detached retina. Overall, efficient rather than inspired, though if you've ever wondered about the commercial uses of bat guano, your answer's here.
