Its primary appeal will be to film-goers who have a love of film which stretches back to the 1940s and 1950s, in order to fully appreciate the rich period detail but also the sly, off-centre humour about an era in Hollywood when the studios and their stars were in decline.
The plot is pretty daft, involving kidnapping, a morally-tormented hard man, a sword-and-sandal epic, dancing sailors, a singing cowboy, synchronised swimming (evoking aquatic film star Esther Williams), British drawing-room drama, overnight marriages, Tilda Swinton in ridiculous hats (evoking gossip columnist Hedda Hopper), and a Russian submarine.
No one is spared the Coens' sharp, satirical eye, including a cabal of 'Communist' Hollywood writers who are treated much less sympathetically than in the recent film Trumbo.
Nevertheless, Scarlett Johansson is once again sublime.
There are unusual moments for a comedy, including a theological debate between representatives of various religions, who concur in the end that Jesus was a 'swell guy'. Highly recommended.
