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 - chronological order
Directed by: Jean-Pierre Jeunet
Starring: Sigourney Weaver, Winona Ryder, Ron Perlman, Dan Hedaya, Gary Dourdan
Revealing mistake: When Hillard throws the basketball at Ripley, you can clearly see the white tape on Ripley's hand which was used to catch the ball. (00:23:10)
Trivia: In the scene where Ripley discovers the room full of failed clones, she stumbles upon Ripley 7, a hideous, malformed but still living clone. The entire scene after she discovers her ill-fated 'sister' is ripped directly from, and is an homage to, one of the most famous deleted scenes from the original Alien. Ripley finds a long dead Brett and barely living Dallas cocooned in the bowels of the Nostromo, and Dallas asks her in a pathetic, painful voice to kill him. She obliges by using her flamethrower. The scene in Resurrection is almost 100% identical, everything from the design of the flamethrower to the emotional reaction and facial expressions she had in the cut Alien scene.
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.
