[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.
