Common Sense Note
Parents need to know that Shanghai is a period thriller meant to evoke the spy/detective movies of the 1940s; it looks beautiful, and the screenplay is ambitious, but it eventually becomes muddled and lost. There are several scenes of shooting, with blood sprays and death, as well as punching and stabbing (and the associated bloody wounds). There's no nudity, but the main character is shown in bed with a married woman and kissing a second married woman, and there's talk of men cheating on their wives. Language is infrequent but includes uses of "s--t," "bastard," and "bitch." A secondary character seems to be addicted to opium; she goes through withdrawals and is injected with a needle. Scenes take place in an opium den, with opium smokers shown, and characters drink and smoke fairly frequently in clubs and at parties.
