Le dernier contrat

This is, indeed, a quiet film with little dialog and few characters. Unfortunately, that style of filmmaking relies heavily on expert acting, an extremely sharp screenplay, and top-notch cinematography to succeed. The cinematography was fine. But the rest, not so much. McGoohan and VanCleef were both fine actors. McGoohan made his career by saying as little as possible so he fits perfectly into this style. But when they're asked to actually speak ... ugh. The dialog is generally hackneyed and stiff. The story elements, in general, were quite cliche'd even by 1979.

Overall I'd recommend watching it if you're a McGoohan or VanCleef fan. But otherwise you won't at a loss for missing it.
