Joss Whedon attended the ninth annual Glasgow Film Festival as part of the European premiere tour of his take on Shakespeare’s Much Ado About Nothing, and the very last question of the Q&A was specifically about whether or not he could see Ruffalo’s Hulk get his own film.
“Yes. But it would be very, very hard. Hulk is a tricky son of a bitch. He’s the Claudio of superheroes. Because the problem is it’s a very popular character, but it’s not a superhero. Half of it’s a superhero, half of it’s a werewolf. And you can’t structure it like a superhero movie, you can’t light it like a superhero movie. How do you develop that? It would be extremely difficult. The one thing you would have in your favour would be Mark Ruffalo. But right now I don’t know if they have plans to do that or not, because he works so well as part of a greater whole, but by himself, it’s tough. I don’t envy the guys who went before.”
