The Big Heat Reviews
A police detective, Sgt Dave Bannion (played by Glenn Ford) investigates the apparent suicide of a senior police officer. A woman approaches him and claims that it wasn't suicide - it was murder. Intrigue ensues...
A great crime-thriller from master director Fritz Lang. While you know broadly who did it, you don't know all the details. Moreover, you mostly see it from the policeman's point-of-view, and feel his frustration as he is constrained in his abilities to crack the case.
Great work from Glenn Ford in the lead role, especially as he is more known for westerns. Good support from Gloria Grahame, Alexander Scourby and an early-career Lee Marvin.
Not perfect - Bannion's big break feels a bit contrived. In addition, the pacing is a bit off: after building the tension, the ending feels rushed. These are, however, minor negatives in an otherwise flawless movie.
