If you want to create movie-credits style animations in PowerPoint, you will miss the Crawl Entrance animation option that was available in older versions of PowerPoint. You can substitute Crawl with Fly In, and change the animation speed to something slower such as 15 seconds, and also set the direction of the Fly In animation to From Bottom. The Star Wars credits style is a variant of the Crawl animation. In this style, the text crawls from bottom to the top, as it also does with Crawl. Additionally, the text diminishes in size all the time until it fades into oblivion. It is a real neat effect, and it is possible to accomplish it in PowerPoint 2013 if you combine multiple animations.
