"September, 1985: “Aliens” finally started shooting on a London sound stage. After all the debate and questions about the budget, Hurd and Cameron brought in their movie on schedule and on budget. The studio loved the dailies and the buzz began to leak out: “Aliens” just might be the sleeper hit of the summer. But there was one more bitter struggle preceding the film’s opening. Fox wanted a movie of two hours or less but Cameron’s print came in at a lengthy 2 hours, 17 minutes. Nowadays, studios rarely release movies longer than 2 hours, 5 minutes, because the length cuts the number of daily screenings from five to four, substantially reducing the box-office take. For Fox to have the extra showing, Cameron would have had to cut 12 minutes. Late April, 1986: As Cameron and Hurd were working on their final “mix” (joining sound and picture together), Rudin flew to London to see their cut. Said Cameron: “We were standing on this London sidewalk and Rudin asked us if there was anything that could be cut. But we felt that if we had to take out 12 more minutes, the movie wouldn’t make sense.” Rudin acquiesced."
