Did You Know?


Writers and special effects artists Irving Block and Allen Adler originally conceived of this film as a B picture and brought it to Allied Artists, which turned it down. They then decided to try their luck at MGM, then still Hollywood's most prestigious studio, which had not produced a science fiction film since The Mysterious Island (1929). To their surprise, studio chief Dore Schary green-lighted the project, immediately catapulting the film to the status of a major production. See more »


When he first meets the cook, Robby takes the cook's bottle of Ancient Rocket Bourbon, pours it into his body, analyzes it and offers to make 60 gallons. Later, when he meets the cook to deliver the bourbon, it's in hundreds of identical bottles all labeled just like the cook's own bottle. But Robby didn't keep the original bottle so should have had no way of duplicating it, let alone its label. See more »


[Lt. Farman offers the brilliant but innocent Altaira some sugar for her coffee]
Altaira: But you keep helping me. After all, you're not Robby.
Lt. Farman: [chuckles] I wouldn't mind being Robby in certain ways. Uh, that's only in *certain* ways, of course.
Altaira: I can see that was probably very clever, but I don't seem to understand it.
Lt. Farman: There's no rush.

"Forbidden Knowledge"
24 August 1999 | by (St. Louis, MO USA) – See all my reviews

I first saw this movie when it originally came out. I was about 9 yrs. old and found this movie both highly entertaining and very frightening and unlike any other movie I had seen up until that time.

BASIC PLOT: An expedition is sent out from Earth to the fourth planet of Altair, a great mainsequence star in constellation Aquilae to find out what happened to a colony of settlers which landed twenty years before and had not been heard from since.

THEME: An inferior civilization (namely ours) comes into contact with the remains of a greatly advanced alien civilization, the Krell-200,000 years removed. The "seed" of destruction from one civilization is being passed on to another, unknowingly at first. The theme of this movie is very much Good vs. Evil.

I first saw this movie with my brother when it came out originally. I was just a boy and the tiger scenes really did scare me as did the battle scenes with the unseen Creature-force. I was also amazed at just how real things looked in the movie.

What really captures my attention as an adult though is the truth of the movie "forbidden knowledge" and how relevant this will be when we do (if ever) come into contact with an advanced (alien) civilization far more developed than we ourselves are presently. Advanced technology and responsibility seem go hand in hand. We must do the work for ourselves to acquire the knowledge along with the wisdom of how to use advanced technology. This is, in my opinion, the great moral of the movie.

I learned in graduate school that "knowledge is power" is at best, in fact, not correct! Knowledge is "potential" power depending upon how it is applied (... if it is applied at all.) [It's not what you know, but how you use what you know!]

The overall impact of this movie may well be realized sometime in Mankind's own future. That is knowledge in and of itself is not enough, we must, MUST have the wisdom that knowledge depends on to truly control our own destiny OR we will end up like the Krell in the movie-just winked-out.

Many thanks to those who responded to earlier versions of this article with comments and corrections, they are all very much appreciated!! I hope you are as entertained by this story as much as I have been over the past 40+ years ....

Rating: 10 out 10 stars
