Throughout the movie?

Or really moving things with his mind?

No. He was having a mental breakdown, and the Birdman was his internal monologue, in fact he was the birdman, that character had become "him"

The stage play was not just a last gasp at stardom it was a last chance for him to prove to himself that he was an "artist" that his work wasn't commercialized garbage, ie that he was Edward nortons character

However, he realized that he wasn't when the final scene kept ending in disaster culminating in his trot around the block in his drawls.

The public didn't give a shit until he was a spectacle. Until he literally shot off his nose to spite his face

In other words he was a joke, a punchline...not an artist. Not some great actor...but a hammy movie star...pretending.

And when he realized that he was...free. And chose to die.


does it really matter?

wonder what bin's doing?
