  • "I was going to be an Easter egg in the background…[there was] a Simon Williams Film Festival, and I was in all of the movie posters."
  • "If you know the Marvel Universe, Simon Williams becomes Wonder Man, becomes an Avenger. So, he’s part of that universe. It was a neat little Easter egg, it was a neat little piece of the universe. It didn’t get into the movie. That’s fine. That happens all the time. I still had the same wonderful experience. But moving forward, I don’t know, let me see what we can do with this opportunity. That’s just a cleverly disguised opportunity. Am I right?"
