I take it you mean Army of Thieves? Because if you're telling me there is a 1962 jazz drama with swearing in it I might change my stance of "No Musicals".

But yeah, it reminded me of how great the heist scene in Rififi is, and how modern (commercial) movies just won't shut up, either through complex sound editing and mixing or with loud music often telling you how to feel (or to your topic, using expletives so you know it's supposed to be funny). Silence is gold, but mining it is becoming a lost art.
