Watching Gosling, usually cast as a cool, detached man of action in such films as The Place Beyond the Pines and Only God Forgives, glide gracefully past Angel's Flight or the Watts Towers reminds us of the way we felt when Christopher Walken was revealed, as a saloon-dancing gangster in Pennies from Heaven, to be a frustrated song-and-dance man.
Old Hollywood is as glorious and intimidating to these 21st-century lovers as it was in Pennies from Heaven when Steve Martin and Bernadette Peters danced in front of the flickering image of Astaire and Rogers, before entering the cinema screen themselves.Something similar happens in La La Land when Mia and Sebastian drive up to the Griffith Observatory after watching Rebel Without a Cause ; it’s as though the movie has spilled over into real life.
