Question: If Hal is supposed to be this flawless computer that never makes a mistake or gives false information why then does it tell the astronauts Frank and Dave that a system will fail when that turns out to be wrong?
Answer: This is gleaned from the Internet: The novel explains that HAL is unable to resolve a conflict between his general mission to relay information accurately and the specific orders requiring him to withhold the mission's true purpose from Bowman and Poole. HAL reasons that if the crew is dead, he would then not need to lie to them. He fabricates the failure of the AE-35 unit so that their deaths would appear accidental. In other words, HAL is asked to lie, and he doesn't take to it very well, to say the least. The conflict between his mission objectives backs him into a corner where he has to make some pretty big (and cold) leaps in logic in order to reconcile the paradox in his programmed orders.
Answer: In the sequel, "2010" it was revealed HAL was programmed with all the information about the mission to the monolith, but Frank and Dave were not. HAL was programmed not to reveal anything until the scientists were taken out of hypersleep. When Frank and Dave tried to uncover the mystery surrounding the mission, HAL was forced to lie in the only way he knew how. He was not programmed to lie.
Question: Mary's attire looks more like 1960s than 1940s. Any info on this?
Chosen answer: This is not unusual in older films. Earlier costume designers were less attentive to historical accuracy and freely incorporated current fashion trends into period movies. It was just an accepted practice and movie audiences back then were often less discerning and/or unaware of inaccuracies. Today's costumers have greater access to historical information, do more research, and strive for authenticity.
Question: Serious spoiler alert, but this has always puzzled me. At the end of Barbarella the Black Queen unleashes "Matmos", an evil energy which destroys nearly everybody and everything in the film. Pygar (the blind angel) escapes, only rescuing two people from the cataclysm: Barbarella and the Black Queen. Barbarella asks Pygar why he saved the Black Queen after all the evil things she did (she even blinded Pygar). Pygar replies "an angel has no memory." I never got the point of that. What did Pygar mean? (In his previous conversation he recalled things that happened before he was blinded, so obviously he did have a memory.) And I could not see the point of or meaning to this ending at all. Did any of this make sense to anybody else?
Answer: You say that Barbarella was beyond lame-it was totally atrociously bad and ludicrous. It was released in autumn 1968, when I was 12, and too young to see it at the cinema. I finally got to see Barbarella when I was 18 and it was shown late one night on television. I wholly concur: I thought it was totally, atrociously bad and ludicrous, and my opinion has not changed since.
Answer: I concede your point. Perhaps I was being a bit too literal. When Pygar says he has no memory, he may not mean that all past events clear from his mind (in the way that, for example, you could delete a computer file from your laptop). Instead, he might mean he does not dwell on the past, or he does not retain bitterness or anger for past wrongs, or he does not return evil on those who were bad to him. I think the film was based on a comic that ended in pretty much the same way. All the same, I always thought the ending was rather lame. It was as if somebody told Roger Vadim (the director) "hey, this film is supposed to be 90 minutes long, but we've done 89 minutes filming, and we still haven't got an ending." So Roger Vadim got the Black Queen to unleash Matmos and destroy everything. (To be pedantic, Barbarella is 98 minutes long, but I hope you understand what I mean.) Personally I thought the ending of "Monty Python And The Holy Grail", where a police force stops the film, was a similar disappointment.
Answer: He's in the same location as Ellis Island. Thousands of years have resulted in significant changes geographically.
