When Liz is good, she's very, very good, but when she's bad, she gives it all she's got. Director Daniel Mann definitely had a way with leading ladies.
The dialogue is rough. Let's say O'Harrowing. And the ending is absurd. But so is most of it for that matter. It's the living it up that gets you in this film.
Alterations made on John O'Hara's 1935 novel by the scenarists (among other things, they have updated it from the Prohibition era, spectacularized the ending and refined some of the dialog) have given Butterfield 8 the form and pace it needs, but the story itself remains a weak one, the behavior and motivations of its characters no more tangible than in the original work.
Once thought of as racy and adventurous in its treatment of sex, this turgid nonsense about a high-class whore with love in her heart has dated atrociously. Taylor hams away and Harvey in his debonair mood is distinctly unappealing, while the overall effect is too excruciating even to be unintentionally funny.
