How Has Technology Changed Movie Making Today?

I chose my topic because I love movies and the process of how they're made. I also love movies from the 80s and 90s, and with that, I knew that they had a long-living legacy in technology changes, which would come in very handy in my project. So overall, when I knew I had a chance to share my movie making knowledge, I knew it was a chance I didn't want to miss.
