Casting Johnny Depp as the fabled Boston crime boss James “Whitey” Bulger didn’t sound, on paper, like the most promising proposition. Depp tends to excel at, and to revel in, playing hyperstylized characters who exist in fanciful filmic worlds: He’s perfectly at his ease as a vampire, a pirate, a blade-fingered freak, or a singing demon barber but can seem uncomfortable inhabiting the skin of real-life people, whether it’s a Prohibition-era gangster (Public Enemies) or a disco-era cocaine importer (Blow).
