Bit-part actress, used by Irving Thalberg as a stand-in for Greta Garbo (at a time, when the star may or may not have been pregnant and was likely to be, at least temporarily, unavailable) for long-shots and at costume fittings. Apparently, Dvorak not only possessed Garbo's exact physical dimensions (height, weight, shape), but was also able to walk and talk (affecting a fake Swedish accent) exactly like Garbo.
