I loved seeing this a month ago, and I thought I'd make a list of my own... I'm still working on it. Ugh.
Good luck with it! It was so hard to narrow it down and a lot of my favourite films don't even feature in here because there were so many to choose from. I really might have to bash out a second 100 just to feel like I've included the majority.I look forward to seeing yours when it's done!
