Married Life (2008)

In an unnamed 1949 American metropolis, meek businessman Harry Allen confides to roguish best friend bachelor Richard Langley that he's about to leave wife Pat for bottle-blonde beauty Kay Nesbitt. As Richard inevitably tumbles for Kay, Harry decides to kill Pat, but finds an obstruction in local poet John O'Brien. Freely adapted from the classic 50s British crime novel by John Bingham, Married Life is that rare thing, a film noir delivered with grim seriousness.
