Zontar: The Thing from Venus
A misguided scientist enables an alien from Venus named Zontar to come to earth in order to help solve man's problems...
This is the second of Buchanan's AIP TV-remakes, this one of Roger Corman's 1956 "It Conquered the World". There's lots to enjoy here for bad-film enthusiasts, including a sleep-walking John Agar, an over-the-top Tony Huston, and a ludicrous alien design that doesn't come close to matching the original's cucumber-on-wheels. On the plus side, we have the great Bill Thurman playing his usual sheriff role. This is probably the most famous of Buchanan's remakes due to it being spoofed on SCTV in the early '80s. The best news is that you can watch this for free right now: archive.org/details/Zontar_Thing_From_Venus .
Made for TV remake of It Conquered the World, padded out to fit a two-hour TV movie time slot. As you might suspect, it rather suffers for that.
Larry Buchanan picked up some work in the '60s remaking earlier sci-fi films for TV to flesh out AIP's TV package. This crummy reworking of It Conquered the World has laughable flying monsters and spaceships, endless scenes of men in suits discussing the situation and an air of desperate poverty. Little is revealed until the very end of the film, at which point the protagonists face off against a bird-like alien. Stupefying in its awfulness.
