    Invisible Narrative

    Incarcerated killer learns to transcend existential boundaries and temporarily abscond from his gaol cell, preying on a vast array of glamorous former Hollywood starlets. Detective Foxworth is baffled by the apparent lack of physical evidence, and begins to speculate on a supernatural cause. Aside from an original premise and a great cast of former 60's sexpots (Powers, Lyon, Hill, Sommer and Parrish), with names like 'Bambi' and 'Candy', there's not much right with this tepid mystery.

    Mother fixated killer Ashmore does little other than look constipated, perspire and affect intense mind grips, while Foxworth's perplexed expression suggests he's struggling with the concept of the killer's meta-physical abilities. As an audience, it was also a struggle to remain engaged, as the movie laboured from one murder to the next seemingly without selection or purpose. Powers is entirely irrelevant to the plot, a vexatious waste of talent simply for the status her name brings to the dull production. Whatever value the original idea had, it quickly evaporates, the all too brief cameos being the only partially redeeming qualities.

    Wasting an attractive cast, "Invisible Strangler" has invisible special effects, paltry production values and incoherent dialogue to match its laborious narrative approach. Female viewers will be less concerned with the bevy of babes on show, and more appalled by the blatant misogyny of the storyline. A disappointing revision of "The Invisible Man" borrows heavily from "Psychic Killer" released a year earlier in 1975, and should have been so much more entertaining.

    Budget "Boogie Man" film.

    This budget "Boogie Man" film was just that.

    I thought this movie was worth watching. Elke Sommer shows some nice cleavage and we get to see Stephanie Powers naked butt. That almost is worth it by itself.

    This is definitely midnight movie fare, but I thought it told a story of an invisible stalker that was almost convincing. This movie embodies the flavor of 1970's budget movies. Stephanie Powers is fun as the cops playful girlfriend. Elke Sommer gets to be the drunk mean witch. The ending left something to be desired, as we really don't know what happened to the boogie man.

    I think this was worth watching. 6/10

    Pretty shabby stuff but quite strange and that's always something

    The Astral Factor is about a psychopath, imprisoned for murdering his mother, who somehow learns how to make himself invisible by studying books while incarcerated in a hospital for the criminally insane. Needless to say, he escapes and goes on a killing spree.

    This one begins quite well in all fairness but it soon gets somewhat tedious. The storyline is such a bad basic idea you have to wonder how the likes of it ever got as far as to be given the green light for an actual movie. Well, while it was made as film, it seemingly sat on a shelf for near enough ten years before actually being released. It's really not all that surprising to be perfectly honest. While the story is pretty terrible, it's not really that that is the chief problem. Sometimes bad stories make for good films after all. No the issue is probably that, with very few exceptions, movies about invisible men are almost always terrible. What can be more cinematically tedious than an invisible character? What it does mean though, is there are some very silly murder scenes which I guess could provide some laughs I suppose. But for me the best aspects about this one were the appearances of Elke Sommer and Stephanie Powers. Sommer starred in a few interesting cult films in the 70's and her presence is always welcome, while it was strange to see future 'Hart To Hart' TV star Powers cavorting about with her butt exposed. She played the detective's trophy wife! She does zero housework and spends all his hard earned cash. She and Sommer were at the very least interesting diversions in a film in need of them.

    Nice Take on the Invisible Man Story

    A convicted strangler, studying the paranormal in his jail cell, learns to make himself invisible. As an invisible man, he escapes from prison to stalk and strangle the five women who testified against him at his trial.

    This film is interesting in that it seems to be like "The Invisible Man" or "Hollow Man", as it follows a criminal who can become transparent. But the plot is quite different -- he can turn solid or clear through the power of his mind, and is actually already in prison when the film begins. This does not involve any sort of scientific experiment, but rather more of a spiritual ("astral") approach.

    Although this is a low-budget crime mystery thriller, it is certainly entertaining and better than I would have expected. I actually found it pretty clever, and really enjoyed the unique angle. Does the killer leave fingerprints? How does he turn his clothes invisible?

    Although I saw the movie on Netflix, it is readily available for anyone who wants to track it down. The DVD has been released into cheap box sets and I think you might even be able to watch it for free online. Whether or not it deserves a new DVD or BD release with features is debatable, and if it is in the public domain, it would probably be hard to convince anyone to do that.

    Bonus: Genre fans might be happy to see Elke Sommer ("Lisa and the Devil") and Marianna Hill ("The Baby").

    The quality was as bad as the quantity!

    I don't understand how you can take some fairly decent actors and make a film that a film student would be ashamed of doing. It had lines through it, as perhaps it was taken from someone's shelf, turned into a DVD with no clean up, and sold. Luckily my copy was with a 6 disc box of "Blood Chillers". Apparently they forgot to preview it before they added it to the collection. Who knows? Perhaps someone's relative was in it!! They story line itself was promising, but Robert Foxworth spent the entire movie overacting, Mark Slade was typecast as the "college boy" with no police skills AND who chewed gum even while eating his hot dog. What kind of Lieutenant on the police force has a hot dog?

    That sums up this film...Foxworth being the severely overacted hot dog.

    • Trivia
      Being a film of mostly former A-list guest stars like Sue Lyon and Elke Sommer, character-actor Frank Ashmore, who plays the central killer/antagonist, is far down in the credits. In fact, his name shows up in the middle of a "stack" of names. This could be because he was one of the few unknown actors in this film, or the fact he's invisible a lot of the time.
    • Goofs
      Barrett tells the crew "Don't forget that telephone" and the following shot shows them with said telephone already in hand, dusting brush poised, so they were already not forgetting it before he told them not to.

      Lt. Charles Barrett: Candy did.

    • Alternate versions
      The DVD version released as "Astral Factor" is a rather different movie from the DVD released as "The Invisible Strangler." The killer is not only seen throughout in "Astral," but talks frequently (as opposed to never in "Invisible Strangler," where he is also invisible after the first scene up until the end) Most of the scenes he is in, including the opening where he first becomes invisible, is completely reshot with a different cast, features different music (as does much else of the movie), has different action, and often strikes a different tone. "Astral Factor" also fills in many missing plot points from "Invisible Strangler" with the inclusion of material edited out from the other version, which are usually easy to spot by grease pencil marks on what is obviously a work print. The running time is about ten minutes longer for "Astral," despite the fact that the opening scene, in its completely different version, runs about that much shorter than the one in "Invisible."
