According to Deadline:
Billy Connolly is to join the cast in the role of Dain Ironfoot, a great dwarf warrior and cousin of Thorin Oakenshield. “We could not think of a more fitting actor to play Dain Ironfoot, the stanchest and toughest of Dwarves, than Billy Connolly, the Big Yin himself.
They go on to say that with Connolly now cast in this role, casting is now complete and after the amazing first trailer for the first part of the 2-part saga, I cannot wait to see it!
