Producer Gail Anne Hurd decided to shoot the film in England because it would not only save money, but also because of the continuity of the film. Most of the technicians who have filmed "Alien" live in England, and they laid a solid foundation for the film. Cameron believes that the appeal of the film lies in its ability to use people's imagination, such as dealing with alien weapons in the film. Cameron said that he did not want to be a slave to the movie, but the weapons in the movie are really attractive. Although Cameron believes that weapons are one of the highlights in the film, Xue Gone Weaver, who plays the heroine Ripley, opposes this. Weaver didn't like weapons. During the shooting, she was exposed to different kinds of strange weapons every day, which made her feel very uncomfortable. She is a member of the American Gun Control Association, and her role in such a bloody science fiction film makes her feel very confused.
In the middle of the filming, Cameron replaced James Lima, who played Hecks, with Michael Bain. Cameron didn't want to say anything more about this. He thought it would be appropriate to use "different artistic viewpoints" to summarize. There was also an accident during the shooting, and a fire broke out in the canopy. At that time, the actors were filming the scene of the retreat to APG, and the flamethrower ignited the studio. Because the set is made of plastic, when it burns, the toxic gas almost suffocates the actors.
