My son is really into playing Disney Infinity (a video game a little like Minecraft that allows players to create their own worlds). One of the sets of blocks you can use in it is inspired by the movie Tron.
My son loves the style of the blocks and this prompted us to have a conversation about the movie and him deciding he wanted to watch it. He gave me some of his pocket money and I ordered a copy on DVD from eBay. It came today and we're watching it now.
The weird thing is, whilst I had a very good idea of what it was about, I now realise that I've never seen it.
Given that I was the perfect age for it when it came out and have loved sci fi movie and video games for most of the 30 years between then and now this seems odd to me.
Which movies are you surprised you haven't seen?
