My favorite scene with Patrick Stewart is him leading the defence of the Atreides palace while being armed with an adorable puppy in Lynch's "Dune". RIP.

There's a funny story in his memoir where he got cast as Gurney Halleck when Lynch saw Patrick in old man makeup in a theater production and had no idea who he was when he showed up for the part.
