The basketball scene (Alien: Resurrection)
One might wonder what a basketball scene is doing in a movie like Alien: Resurrection, but it definitely served a certain purpose. It was to showcase just how badass Ripley had become, thus, directors created a scene where Sigourney Weaver had to make a really tricky shot without even looking. The scene was supposed to be CGI, but Sigourney Weaver just went and did it for real. It took her a couple of takes, but she did it nonetheless!
