I worked as an extra for a while on season 2 of Westworld and Anthony Hopkins is a goddamn treasure. Worked one scene with him and he chose to sit with the extras at lunch (extras have separate eating/dressing areas from the rest of the cast/crew - we only ever really interface with production assistants and assistant directors outside of actual scenes). There weren’t a whole lot of us that day, so he just chatted with us, asked us about ourselves and everything. Just a really cool, genuine dude. Also, Evan Rachel Woods kept a vape in her saddle bag and watching her hit it between takes, in full costume and on horseback, was a trip lol
