This of course was the first movie i saw by the infamous Z-Grade Master Larry Buchanan. I saw It Conquered The World (1956) the monster was kinda stupid looking in the original but it was made like that for Venus gravity reasons, i still enjoyed the original being a B-Movie Buff myself & it was by Roger Corman one of the most well known Producers & Directors of Sci-Fi & Horror Cinema. Well I read about Buchanan's Version on the net saw screen caps & all I thought the monster in this remake looks better so i asked for it for my Birthday in September of 2001 i got it & watched it. I knew John Agar from other Sci-Fi & Horror Flicks he was really good in this one the other acting was alright not as good as him though of course i still really enjoyed it. As we all know Susan Bjurman of course was no Beverly Garland at the role & not as beautiful as Garland, but she was good at the acting part. Tony Houston was good but he was no Lee Van Cleef. Pat Delaney was as good as Sally Fraser & as beautiful i thought. The original was better in some ways & Buchanan's version was better in other ways. So overall I really liked it.
