I am not a big movie buff but there are a couple of films that you absolutely must see and both of them star Anthony Hopkins and Brad Pitt, together: Legends of the Fall and Meet Joe Black. They are two of my favorites. Actually, they are family favorites.
The stories are deep and full of love and loss. The relationship between Hopkins and Pitt is intimate and complex in both movies. I don't want to share more than that for fear of ruining it for you. But I must warn you... of course they are romantic in nature. It will be a few years before you can see and appreciate them. I hope we get to watch them together.
