Character mistake: When Ripley asked the doctor how they "got" her, he replies from blood samples on Fury 16. This is in reference to the planet in Alien 3, but it was called Fury 161. (00:11:00)
Alien Resurrection (1997)
1 character mistake
Directed by: Jean-Pierre Jeunet
Starring: Sigourney Weaver, Winona Ryder, Ron Perlman, Dan Hedaya, Gary Dourdan
Continuity mistake: Ripley kills the alien in the corridor after it has killed the first member of the Betty crew but there is no melting of decks or bulkheads from the creature's acidic blood. Also, the Betty crew seem unaffected by all the acid. (00:46:00)
Trivia: Purvis is one of the human hosts for an alien and it rips through his chest on the betty. In an episode of The X-Files, the man who plays Purvis plays a scientist who is a human host of an alien which burst through his chest.
Answer: In Alien 3, Ripley discovers there was an Alien queen embryo growing inside her, so she chose to kill herself. By cloning her, scientist were hoping the Alien queen embryo she had in her at the time of her death would also become cloned, which finally happen after the 8th try. This is also why the Alien queen they extracted from Ripley has some human traits.
