The Mask of Dimitrios follows Peter Lorre as a crime writer trying to piece together the life of a dead master criminal, finding his steps dogged by a mysterious man played by Sidney Greenstreet who has his own reasons for finding "Dimitrios". While the two of them are great, and I'm certainly happy to see Lorre in the hero's role, the film promises better revelations about Greenstreet and Dimitrios than what we ultimately get. I definitely had a "that's it?!" reaction. Without a clever resolution, its structure's use of long flashbacks to tell Dimitrios' story just makes it feel like a series of barely connected vignettes. I recommend it for the principal actors and the noir atmosphere, but I don't think the novel it's based on makes for that good a film.

Superb spy thriller..
But it has Sydney Greenstreet and Peter Lorre in it - how could it not be?
