124 minute running time but doesn’t feel overly long because it’s so much fun … works as both a comedy and a thriller … it’s hilarious but also serious with the grime of early 1970s New Yawk and the violence and horrific killing … helped hugely that Matthau was a native New Yorker. This is a green-go, one of the best thriller-comedies of all time. John Farr also recommends it.
