I'll sheepishly admit to having seen NO version of the apparently VERY popular Willkie novel until seeing the Andrew Lloyd Webber musical adaptation on Broadway recently. Came out of the Marquis Theater with a passion to see ALL prior adaptations, and this delectable one is my first. LOVED it! Without doing any "spoilers," let me advise others like me who are seeking this out in the wake of the musical that the musical cut one MAJOR character, that being the Countess Fosco (played here with breathtaking abandon by the fabulous Agnes Moorehead), and despite several story alterations to the musical that I appreciate (it's a bit more emotionally gripping), the Countess might have helped improve the musical. But mostly I'm coming here to make a statement of appreciation for the great Sydney Greenstreet, whose Count Fosco is simply as masterful a portrait of evil as I've ever seen, and a career peak for one of the cinema's greatest character actors. Only problem with the film, whose cast is wonderful in its entirety, is that at its finale, it just sorta trickles away into a forced and artificial-feeling happy ending that I just KNOW couldn't have been in the novel. Otherwise, a swift and engrossing 109 minutes.
