Penn was referring to “Birdman’s” Mexican writer/director/producer Alejandro Gonzalez Inarritu, who directed Penn in “21 Grams.” The joke didn’t go over well with some on Twitter, who went online to voice their outrage.
But asked backstage about it, Inarritu said, “I found it hilarious.”
He went on to say, “Sean and I had that kind of brutal relationship where only true friendship can survive. When I was directing him in ’21 Grams,’ he was always making jokes … I made a lot of very tough jokes (to him) that I will not tell you.”
In short, Inarritu said, “I didn’t find it offensive, I thought it was very funny.”
Inarritu was also asked if he was really wearing Michael Keaton’s underwear from the film for good luck, as he had joked about in his Oscar speech. “I wish I was in a more intimate setting to prove it,” he quipped.
