What made the film adventurous was that he did it as a musical, with existing song from generally the 1930s interpolated in -- and all performed by actors and actresses who were decidedly not singers or dancers. The results are mixed, but fun.
The two numbers I showed were largely singing. So, I thought it might be fun to see a bit o' the dance. Most of the actors here aren't especially well-known. Adrian Lester might be recognizable to some who watch the British import series Hustle, as a the leader of a bunch of con artists. But you most definitely will recognize that world renown non-dancer Kenneth Branagh, who actually acquits himself nicely, as do they all.
And so here they are singing -- and dancing the light fantastic, "I'd Rather Charleston."
