7. Alien - It Was Horrible, Like A Chicken
If there was a movie that would be the prime example of changes that occur during the pre-production of the film, that one would be Alien. The name of the movie was different (at first it was Memory, then it was Starbeast, and at last it was Alien), the characters were very different, the design of the alien (shown above) was much more different, and while most of the story remained the same, some things changed a lot. The basic story was pretty much the same that was shown in the movie; A spaceship that comes back from a mission receives an S.O.S. message from another planet and they go to investigate, only to realize that they've brought back an alien and that they were trapped with him with no possibilities to escape. Along the changes made was than at the beginning all the protagonists were male, the alien was disposed in a different way and, some scenes involving the alien were very, very different. In one of them (one that would have been cool to see in the movie) involved to have the Alien using another member of the ship as a human shield. Another scene would have been more hilarious than terrifying; It would have been when the grown alien was introduced, he ripped off the head of a member of the crew while the body was still moving. And while explaining this to the crew, he would have said "It was horrible -- horrible. Like a chicken." No,
I'm not kidding. How much it would have changed the film? That line alone would have been enough to ruin the film entirely. It would join the ranks of unintentionally funny moments from movies. There would be no way for anyone to listen to that and still taking the movie seriously. I mean, it was supposed to be a horror movie, right? You don't use "Horrible" and "Like a chicken" in the same line. Thankfully, that line was erased from the final script, H.R. Giger was chosen to redesign the creature, and we all got the classic Sci-Fi horror move that we all know and love.
