Although low-budget and frequently fairly shoddy The Killings at Outpost Zeta has some interesting ideas (though fairly similar to films like Alien) and some genuine suspense.
An elite team (including Gordon De Vol and Jacqueline Rey) is sent to a distant planet to find out what has happened to two earlier expeditions which are missing presumed lost. Once on Zeta the team discover a load of horrifically decomposing corpses and the team then start getting bumped off by a mysterious alien creature...
It is quite silly, and the sets look made out of tin and cardboard but it isn't that bad a film. One interesting aspect of the film is the acting, the actors frequently pause awkwardly and mess up their dialogue. Oddly the effect is quite realistic.
