Dancing Down the Stairs
I`ve seen this film a hundred times (well maybe not that many) and every time I see it I wait for the last reel when Cagney leaves the Presidents office and dances down the stairs.
It feels so improvised and utterly a feeling of how thrilled George is at being honored by the President that you can`t help but feel an empathy with him and his happiness. He was one of the greats and this scene shows why.
