A very disjointed British exploitation flick...Which as other reviewers have said seems to have had production troubles...

The poker sequence which takes up the first 3rd of the film seems like a later addition to try to stick the rest of the film together. As it involves Yutte Stensgaard topless and looking stunning i'll let it slide that it's at least 10m too long...Robin Hawdon spots a stick on moustache in this part briefly...Did he shave the one seen in the flashback sequence off and have to fake it...or is it fake for the whole film?, as for his acting it ranges from wooden to well...more woodern!

James Robertson Justice and Charles Hawtrey play...well, they are supposed to be baddies but what then does that mean for the Angvians?...Mr. Justice realizes that he's in a piece of rubbish and at times gives up even trying...Charles Hawtrey in between Carry on Camping and Again Doctor is given little to work with...both actors break the 4th wall at times as well, maybe looking for forgiveness from the audience. Justice just disappears near the end...the last section seems to only exist to get more nudity into the film.

The action sequence in the woods is oddly entertaining with the Angvians using their fingers as weapons...

Best Sequence - The lift...and the bits with Yutte looking stunning.

As I say I'd love to know the true story of it's making.

I believe I first became aware of this sci-fi/sexploitationer via the biography for actress Valerie Leon included among the extras on the Anchor Bay DVD of Hammer's superior BLOOD FROM THE MUMMY'S TOMB (1971); incidentally, the film under review was made by rival company Tigon.

To begin with, the script was apparently inspired by a comic strip (such cinematic adaptations were all the rage at the time – no doubt, the makers were encouraged by the success of BARBARELLA [1968]). Still, even reading through the cast list, I knew not to raise my 'artistic' hopes too highly – given that it featured both James Robertson-Justice and Charles Hawtrey, stalwarts of (respectively) the popular "Doctor" and "Carry On" comedy franchises…who actually turn out to be the villains of the piece!! The narrative drew heavily on another then-current fad i.e. espionage – in fact, the hero is a stud-like albeit laid-back secret agent who naturally proves irresistible to the alien women (actually, an alternate moniker for the film) the titular figure (played by veteran Dawn Addams) sends his way in order to derail his investigation into the abduction of several earth girls.

That said, the plot is barely there and becomes especially confusing – not to say silly – during the latter stages; for what it's worth, the film culminates in a chase wherein the otherworldly gals kill virtually all of their male pursuers simply by pointing their fingers at them (accompanied by the incongruous noise of gunshots)!! Needless to say, ZETA ONE's raison d'etre and prime asset is its relentless parade of innumerable but anonymous starlets of the era in the nude or otherwise scantily-clad: the above-mentioned Valerie Leon herself is underused, but fellow future Hammer lead Yutte Stensgaard – who engages the hero (to whom he's recounting his non-exploits) in a lengthy and decidedly irrelevant game of strip-poker – comes off quite well (no pun intended). Also worth mentioning are the low-budget but appropriately psychedelic sets and the title tune (featuring a reasonably effective guitar riff).

This is one of those "so bad, it's good" movies that you encounter from time to time. Admittedly, it doesn't start 0ff very promisingly, but it gradually gets down - or rather gets off - to business, although the "business" is periodically interrupted by Charles Hawtrey (presumably he was not required on the "Carry On" set that day) and James Robertson Justice (obviously not one to rest on his laurels but willing to pick up any assignment, no matter how trite!) Despite the delightful abundance of feminine flesh, the screenplay doesn't make much sense - indeed some of the scenes - as well as some of the actors - seem to be playing against each other. I watched the movie twice - in case I'd fallen asleep and missed something (I do like to be thorough) - but it still didn't make much in the way of sense. At least I'm not alone. Obviously both the movie's barber and its dress designer did not have a clue either as to which scenes were which and who was wearing what! Available on a very good Salvation DVD. (You heard me!)
