"Seven Sinners" is a decent, light-hearted comic romp, first and foremost a vehicle for Marlene Dietrich, with John Wayne as a co-star. Dietrich plays "Bijou", an entertainer at the title island nightclub who is always being deported from various islands because trouble tends to always follow in her wake. (Such as the barroom brawl that plays out behind the opening credits.) Here, Bijou is wooed by an easygoing Navy captain named Dan Brent (The Duke), just one of the people who's fallen under her spell. The latest trouble arises in the form of a character named Antro (Oskar Homolka), a smooth yet menacing type.
The first-rate supporting cast also includes Albert Dekker as an initially gruff ships' doctor, Broderick Crawford as a well-intentioned lug, the luminous young Anna Lee as the governors' daughter, Mischa Auer as a magician who has a tendency to steal anything that isn't nailed down, Billy Gilbert as harried nightclub boss Tony, Samuel S. Hinds as the governor, and Vince Barnett as a bartender, et al. The Duke is quite engaging, and he and Dietrich do make a good pair. Basically, this very lively comedy does showcase the sexy Dietrich very well, giving her the opportunity to belt out a few numbers.
Overall, "Seven Sinners" offers nothing really substantial, but it IS entertaining to watch while it lasts; it's Homolka who injects tension with his mere presence. You just KNOW that this character is going to be a real problem. Crawford and especially Auer tend to steal the show whenever Dietrich is not around. This may not be the best team-up of Dietrich and The Duke, but it delivers undemanding fun for a little under an hour and a half.
Six out of 10.
