Chatting with the press about the praised Cabin in the Woods horror film, in which he produced and co-wrote, Joss Whedon detailed with Den Of Geek his relationship with Marvel Studios. Essentially discussing how much freedom he was given on the much-anticipated superhero spectacle The Avengers, here's what he says!

"They really did let me make my own film. They said, ‘here are the things we need; here is the villain, we want this to happen; we need the conflict here; here’s the third act, it will involve the following’. Which I’m fine with. That’s great, give me the parameters, because then I know where I’m going, and it does some of the legwork for me. And I know what their agenda is in terms of style, and what we’re delivering, in terms of thrills and the adherence to the Marvel universe, with which I’m very familiar."
"But it was like comics, because they didn’t interfere. I told them ‘this is the kind of movie I want to make’, and they said ‘all right, make that movie’. And that is what happened. And they were as unmeddlesome as any studio I’ve ever worked with, even though they had the very strict touchstones that had to happen. So it was a weirdly free experience."
