This is a sumptuously-staged costume drama, the kind Hollywood always did so well. Only there's a dark side to "The Great Sinner", as the richness of the production begins to coexist with sordid tales of gambling addiction and related human tragedy that soon unfold. No one is immune here; even stolid Gregory Peck falls to the lure of the cards, and hard. Ethel Barrymore is subtly wonderful, as ever, and steals every scene. This becomes a powerful, suspenseful film with a fine cast and a relentless tale to tell. Not to be missed!
