Lol they're all so funny with each other just slagging him I love it. They don't take themselves too seriously. After a broken back I'm sure this injury was a cake walk for Orlando
They're making fun of him, and don't get me wrong, it is funny. They're clearly all friends taking the piss out of him. But a cracked rib is actually _extremely_ painful. Some of the worst pain imaginable. And they take weeks, if not _months_ to heal. Even breathing becomes agony. I don't think they really understood just how much pain he was probably in.
Nope, true. Pretty sure that's actually what they're talking about when they segue into this clip. Also, that scene where the Uruk-hai throws a knife at him and he swats it away with his sword? The knife was supposed to miss him completely. Pure Viggo badassery.
