Movies don’t exist in a vacuum. Each MGM movie is a tiny piece of a large, colorful (although often black-and-white) quilt, with threads tying it into all of the rest of that studio’s product, going forward, yes, but also backward, and horizontally, and three-dimensionally across its entire landscape. Not necessarily a “best of” compilation, this book discusses the films that for one reason or another (and not all of them good ones) changed the trajectory of MGM and the film industry in general, from the revolutionary use of “Cinerama” in 1962’s How the West Was Won to Director Alfred Hitchcock’s near-extortion of the profits from the 1959 hit thriller North by Northwest.
