Marlene Dietrich and Ray Milland were perfect in their roles: Dietrich as a Gypsy and Milland as a British Colonel who is aiding a fellow countryman in obtaining a poison gas formula prior to the start of WW II. As one might expect from two of the world's popular stars, this is not a huge "Hollywood" film but it has all the ingredients of a story that will carry you away to a place you'd never expected to be. The plot is solid, the direction by Mitchell Leisen is superb, the acting is flawless and you will recognize several of the character actors who also played their roles beautifully. I see this as an unexpected treasure and rate this among their finest films.
