As well as having to rustle up a spectacular sequel to The Avengers , it's easy to forget that Joss Whedon is also a creative consultant for all of Marvel's big-screen productions.
That role recently called him into play on Thor: The Dark World , with director Alan Taylor revealing how Whedon was flown to the London set to help out with a couple of tricky scenes!
"Joss came in to save our lives a couple of times,” says Taylor. “We had a major scene that was not working on the page at all in London, and he basically got airlifted in, like a SWAT team or something.
"He came down, rewrote the scene, and before he got back to his plane I sort of grabbed him and said, ‘And this scene and this scene?’ And he rewrote two other scenes that I thought had problems
"Then finally we let go of him, he took off again, and we shot the scenes; and they were just much better and much lighter on their feet.
"I can relate to guys who come out of the TV world, since that’s where I come from. And being able to land and work and solve a problem quickly… I really was grateful."
Sounds like Whedon is becoming something of a superhero himself over at Marvel. Thor: The Dark World will open in the UK on 8 November 2013.
