James Cosmo (The Old Bear/Jeor Mormont) was in Braveheart as Campbell AKA Hamish's dad. Really weird as he somehow looks older in Braveheart than he does in GoT. There was a movie called The Last Legion that was released a few years back that is absolutely hilarious in hindsight. Practically every other scene has at least two actors from Game of Thones on screen together.
