Joss Whedon came up with the Avengers sequel in a 45 minute drinking session in a London pub.
Whedon was reportedly struck by inspiration as he sat in a U.K. bar and filled a notebook with his ideas for Avengers: Age of Ultron.
Despite initial hesitation about a return to the blockbuster franchise, Whedon eventually realized he wanted to write the second film.
He tells SlashFilm.com, “I didn’t actually want to make the film necessarily. I was ragged from the first one, and so I just turned off my brain. I was like, do not think of cool ideas for the next one. Just get through this. But after a few months when they talked about, um… This is now something that makes sense in my life; do I have anything to say?
“And so my agent calls, I was in London, and he called me and said there’s a deal that’s worth talking about – time to start to think about whether there’s a movie. And I’m going, all right. I went to a pub and sat down with my notebook, and about 45 minutes later, my notebook was filled. And I texted my agent ‘yup’ and I have so many things to say and I was kind of surprised. It took me unaware. It was very beautiful.”
