Peter Lorre and Sydney Greenstreet are both fun to watch and have an enjoyable back-and-forth, Zachary Scott is fine, the situations are generally interesting, the film has a good aura of mystery to it. I don't have any complaints (the third act "reveal" is extremely obvious from the get-go, but so what?). It just didn't grab me that much. It's a pleasant way to pass some time, but I doubt any of it will linger with me and I feel no burning desire to see it again.

Okay thriller based on a great novel. Hamfisted direction and dated in some respects but carried by some very good acting from Greenstreet and Scott. Lorre, however seems miscast.

Tremendous beginning, but then it bogs down a bit in the middle and becomes awfully talky. Good cast, although Lorre does get rather shticky in places with his comic touches. Greenstreet and Scott are superb (the latter's lurking malevolence reaching Lee Van Cleef proportions).
