All praise Grail
Dude you gotta see Inside Llewyn Davis and Suburbicon and you really have to see The Two Faces of January (which has one of my favorite actors Viggo Mortenson). But you're right. Oscar Isaac, although a fine actor in the right role, will not only be inevitably miscast in Dune but he's also already getting the same burnout treatment that Adam Driver is suffering from (or more accurately, I'm the one suffering). Does he have to be in everything. These guys must have great agents.Now, I've only seen Isaac in Arrival, Ex Machina, and Star Wars, but I've never seen any facet in his range that would make him a good Duke Leto Atreides.
