[EX Q]: 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.

[EX Q]: Passage: The Egyptian collection consists of about fifty itens, including some objects which stand out in the context of Brazilian museums, due to their quality and rarity.
