SPOILER: Gritty & nerve-wracking. The script by blacklisted writer Abraham Polonsky (who used a "front" for this film) is downright disturbing from the first line (picking up an African-American child, Ryan tells her: "You little pickaninny. You're gonna get yourself killed flyin like that.") to the last (referring to the two indiscernibly charred bodies, one Black, the other white: "Which is which? Take your pick.")
Another solid effort from Wise. At times it feels like it might reach the level of other great heist noirs like The Killing or The Asphalt Jungle, but it never quite gets there. Even so, it's a beautifully shot film and also very good. And the social implications of the film are important when putting it in historical context as well.
The anti-racism message is a bit obvious, though for a 1959 society (and today, even) that was probably a good thing. John Lewis' jazzy score is at times classy and suspenseful, similar to what Miles Davis did for Elevator to the Gallows around this time. Overall a decent heist/desperate men film.
