As an almost fetishistic architectural time capsule shot with a designer's sense of composition, it's mesmerizing. As an Ann-Margret film, you could hardly ask for more from her, even if she's not on screen enough. As a spy pastiche and Dean Martin film, it's somewhere between embarrassing and unwatchable. I suggest muting Dino's Trevor Howard-esque slurring and playing David McCallum's jazz album instead.
Entertaining Matt Helm adventure brims with swinging 60s kitsch. The plot is nothing special, some of the gags cheesy, and the pacing is surprisingly slack. But with a cast that includes Ann-Margret at her feistiest and Karl Malden as the villain, several memorable, fun moments (including Margret's bizarre dance marathon and a hovercraft chase), and Lalo Schifrin's great jazz score, it's decent camp entertainment.
