Sunrise is regarded as one of the last great silent movies, and Academy awards aside, it's easy to see why. Film had come a long way by 1927. Director Murnau manages to pull off both technical and creative brilliance in the form of (mostly) naturalistic performances, some outstanding montages and animated inter-titles to realise an expressionistic world which is by turns horrific, amusing and romantic. Gaynor as The Wife, who resembles Drew Barrymore at times, gives a particularly emotionally deft performance.
Some silent film tropes never quite go away though as the rescue dog makes an appearance, but this time it is subverted to add additional suspense.
Verdict: Silent and deep.
