I have a dear friend who worked on Jeunet's Alien Resurrection set. He had nothing but praise for Sigourney Weaver, and most everyone else. But Jeunet often mistreated the crew, while giving preferential treatment to his own French crew. It sometimes got so bad that Sigourney had to stand up for the crew against Jeunet.
Reading how Jeunet talks about the production - I can see how his "us vs them" mentality affected everything.
