Passage: The Dhoom series began with the release of Dhoom in 2004. The film became a commercial box office hit and received generally positive reviews from audiences, but not so much from critics. As a result, producer Yash Chopra announced plans for a sequel, titled Dhoom 2: Back in Action. John Abraham, portrayer of Kabir Sharma, the villain of the predecessor, was eliminated from the sequel because Chopra did not want Dhoom 2 to repeat the stories featured in its predecessor. Instead, Hrithik Roshan and Aishwarya Rai were introduced into the franchise as the sequel's main villains. Aishwarya Rai's character was summarised as Catwoman, a female fictional comic book femme fatale or anti-hero . Rai stated, "All I can tell you is it would be nothing like anything you've seen me do before." Producer Aditya Chopra told Rai to lose weight after she gained it for her role in 2004's Bride & Prejudice. Yash Chopra stated, "But yes, the role does require Aishwarya to convey oodles of sensuality. She has asked for a couple of months to get into shape. We (at Yash Raj Films) are very clear about every character in every script and what's required of the actors. Before Dhoom, Esha Deol was specifically briefed about the look and the attitude she needed to cultivate. She readily agreed, and look at what Dhoom did to her career!" Roshan also lost twelve pounds of weight at Aditya Chopra's request. With the exception of Abraham and Esha Deol, all of the other main actors in Dhoom were hired again for Dhoom 2.

Passage: After completion of the film Dark Star (1974), writer Dan O'Bannon wanted to develop some of the ideas and create a science-fiction action film. Provisionally called Memory, screenwriter Ronald Shusett collaborated with O'Bannon on the project, adding elements from a previous O'Bannon script, Gremlins, which featured gremlins causing mayhem aboard a World War II bomber. The duo finished the script, initially titled Star Beast it was changed to Alien after O'Bannon noticed the number of times the word "alien" occurred in the script. Their script was sold to Brandywine Productions, which had a distribution deal with 20th Century Fox. The writers anticipated a low-budget film, but 20th Century Fox was inclined to invest millions, thanks to the success of Star Wars. The original script featured an all-male crew, including Ripley character, with Tom Skerritt attached, with the caveat that the roles were interchangeable for men or women. When Fox president Alan Ladd Jr. and the producers at Brandywine were made aware of Fox working on other titles with strong female leads, Skerritt was cast as Captain Dallas and Ripley was recast with Veronica Cartwright, before director Ridley Scott opted for Sigourney Weaver shortly before filming.
