Birdman o (La inesperada virtud de la ignorancia)

Because the movie was carefully rehearsed and shot in sequence, editing took only two weeks.

When Riggan goes back to the theater after a drunk night out, right after he's touching ground beneath his feet again, there can a couple be seen walking from the left side of the frame to the right, away from the camera (we can only see them from behind). When Riggan passes the couple the right man can be seen making a very sudden quick (and very unnatural looking) hand-movement in direction to Riggan's back. This movement might have been necessary to detach the cables from Michael Keaton's back that he needed to be attached to for the flying scene.

Begin and end credits are presented in a peculiar style with the rhythm of the drums

The Sundance TV broadcast removes the swearing and crops the scene featuring Edward Norton's butt so that it is not shown.
