There's an ace Tumblr called Awesome People Hanging Out Together. If you haven't seen it, do. This picture, though a modern day equivalent of their brilliance, deserves it's place right there.
It shows the moment Arnie and Sylvestser Stallone bumped into each other when they both needed treatment for stunt-related injuries.
Arnold said: "After all the action, stunts and physical abuse shooting The Expendables 2 and The Last Stand, it was time for a little tune up on my shoulder. Look who was coincidentally waiting in line behind me for his shoulder surgery.
'Now we're ready for another round of great times and action when we shoot The Tomb.'
Oh. And there it is. Probably a pure publicity stunt. Oh well, sod it, it's great.
