This isn’t exactly huge news at this point, but there seems to be some discussion about how crazy Mark Hamill’s beard was for the film itself. This is what Mark Hamill looked like when they filmed his sequence for Star Wars: The Force Awakens. It appears that Robert Berney (featured in the picture with Mark Hamill) is in the Irish Navy and manned the boat that took the cast to the set.
So that is what Mark Hamill looked like the when he filmed his scene with Daisy Ridley for Star Wars: The Force Awakens.
Thanks to Christopher for sending the photo and to Robert Berney for sharing the picture on his Twitter!
