First time I’ve seen this 1953 film and I like it a lot.  Never been much of a Widmark fan but he’s fine as the anti-hero pickpocket. Thelma Ritter steals every scene she’s in, and Jean Peters makes the most of a poorly developed role. A good remark about Widmark’s character: “He’s got something decent trying to crawl out of him.” The maguffin is a strip of microfilm with industrial secrets that the “commies” have stolen. Widmark picks the wrong pocket and off we go.
