Whedon: My Avengers sequel doubts

Joss Whedon has revealed he had an epiphany about the Avengers Assemble sequel - in a London pub.

The filmmaker directed the successful first instalment of the Marvel superhero movie, but wasn't sure if he wanted to make a follow-up film.

He told the Co.Create website: "There's a business aspect to it and I would be disingenuous not to say that, but the question for me is, do I have another story to tell about these people?

"So we worked on the business side of it and I didn't think it was going to happen - I was like 'I'm never going to do this again.' But once they worked on the business aspect of it I thought that seems fair and cool, so the question was, Do I have another thing to say? I was in London and I went to a pub and had some fish and chips and a pint and started writing in my notebook.

"I'm writing if I was going to do this what would I say and 40 minutes later I filled the notebook. So I texted my agent and said to make the deal."

Joss joked that he was entering a "room of fear" as he approached the star-studded sequel.

"I'm so in love with that universe and the characters and they way they were played and I have so much more I want to do with them. I know I can't match the success of the first one but I can try to make a better film and that's what I'm excited about, that's the new room of fear I'm entering now," he said.
