Det verkar inte ha varit så. Läsning Kirsten Acunas affärs Insiderartikel, Det tog Michael Keaton ca 27 sekunder att bestämma sig för att vara i 'Birdman' :
During a panel at New York Comic Con for the film, Keaton shared the story of how he was cast in director Alejandro González Iñárritu's movie about a washed-up actor, Riggan Thomson (Keaton), hoping to rejuvenate his career with a Broadway play.
Keaton said he first learned about "Birdman" while filming another movie, which he flew home in the middle of shooting to discuss.
"I got a call saying, 'Alejandro was making a movie,'" said Keaton. "I was working on a movie and they said, 'well, unfortunately, you probably can't fly home because you're in the middle of making this movie' and when his name was mentioned, I said, 'Well, maybe I should find a way to fly home because, like I'm sure Edward [Norton], I'm a big, big fan of his movies."
The actor said it took him less than 30 seconds to decide to star in the movie after dinner with Iñárritu who has made movies including "Babel" and "21 Grams."
"So, it was that simple. I flew home and they wouldn't ... they couldn't tell me what it was about and now that I've done the movie I understand why they couldn't explain it because I'm not sure what happened," he said.
"I went and had a dinner with him [Iñárritu] and it was very pleasant and very interesting," Keaton said. "If you've ever spoken with him, you'd know why. He's just a very interesting, extremely passionate guy which is contagious. At the end of the evening he said, 'Well, here. Read this.' It took me about, I don't know, 27 seconds to decide, 'Yeah, I want to do this.'"
Om det hade varit specifikt "skrivet med Keaton i åtanke", skulle han ha varit aktivt hovad. Om denna artikel (och Keaton själv) ska tros, äcklade han med Iñárritu och endast då fick manuset att läsa och acceptera det. Hade det skrivits "för honom", verkar det troligare att de hade kontaktat Keaton (eller hans agent) direkt, och han hade varit med på det från början.
