Another gem from YouTube, Quicksand is a classic storyline...
His descent is sped along by his heartless and morally lacking boss Oren Mackay (Art Smith), and the seedy owner of a penny arcade on Santa Monica Pier, Nick Dramoshag (Peter Lorre). Brady and Vera split when Vera purchases a mink coat with money Brady has stolen. Brady's still-loyal but unappreciated former girlfriend Helen (Barbara Bates) then reenters the scene and tries to woo him back. Later fleeing what he believes will be a murder charge, Brady carjacks a sedan which happens to be driven by a sympathetic lawyer (Taylor Holmes).
By movie's end Brady is back with his faithful girlfriend, who promises to wait for him while he spends the next few years of his life in prison. (from Wikipedia)
