Seeing this one in prep for an interview with the title character. I remember interviews with Michael Keaton in the ’90s as being singularly unpleasant. He made people cry. Not me, but other journalists.

It was all because of where he was, how far he had fallen from what he had been. That’s why “Birdman” has everybody so worked up. He takes on this has-been/used-to-be “Batman” thing pretty much head on.

Or was given a vehicle to do just that by Alejandro Gonzalez Inarritu.

An all-star supporting cast (Naomi Watts, Edward Norton, Zach Galifianakis, Emma Stone) helps realize this take on hasbeendom, subtitled “The Unexpected Virtue of Ignorance”).

“Birdman” opens in a gradual rollout in a couple of weeks.
