My DVD describes Madame Sin as 'a prime example of the camp spy genre'; how misleading! Yes, there are some crazy futuristic inventions used by the baddies to achieve their nefarious goal, but the film as a whole is actually rather sober affair, especially considering the impact of the unexpectedly bleak ending.
Bette Davis plays the titular character, a criminal mastermind who lives on a remote Scottish island from where she conducts her wicked money-making schemes. Robert Wagner is ex-CIA agent Anthony Lawrence, who is abducted by Sin's henchmen and used as a pawn to assist in the stealing of a Polaris submarine, which the villainess intends to sell to revolutionaries.
Rather than a garish, cheezy romp full of outrageous set pieces and witty one-liners from the hero, writer/director David Greene plays much of the film surprisingly straight, even going so far as to add an avant-garde vibe to early scenes, taking the film firmly out of the realm of Matt Helm or James Bond. A bizarre electronic score only adds to the off-beat atmosphere.
Depicted as such, the film sometimes feels frustratingly dreary and uneventful: one longs for an exotic location, a desperate shootout or an exciting car chase to alleviate the tedium that occasionally sets in as Lawrence tries to thwart Sin's plans.
