One of the funniest things I ever heard was in an interview with Jean-Pierre Jeunet where he said that on one of the first shooting days for Resurrection, he realised his main role on set was to "modify the screenplay" so it better suited Sigourney Weaver's vision of the film... Seriously - some of the best material from Joss Whedon's script is still on the page. Unbelievable. By the way... Alien 3 rules. Both cuts.
