Michael used to be a superhero in a few Birdman movies, and now that's what he's known for. But he's struggling to be taken seriously as an actor by writing, directing, and starring in his own Broadway play. The play itself is immaterial as far as the movie is concerned, but the actual production of the play is very important.
Speaking of production, this movie is beautifully shot. It has some of the longest sweeping shots and unbroken scenes I've seen in a long time. There was a particularly good scene where Keaton's daughter, played by the talented Emma Stone, has a straight talk with her father about his irrelevance in the modern world. It's a touching and emotional scene, and I have no idea how both actors managed to stay in character for the entire length of the scene, but there were no camera breaks or cuts visible. I say visible, as it is pretty clear that they use some trickery when it comes to this kind of filming. They have unbroken moving camera shots that cannot happen and had to have been beautifully digitally stitched together.
Keaton struggles through the entire movie with his inner monologue that represents Birdman and everything he was. It is his ambition, his ego, and the voice that always tells him what he thinks of as the truth. Often when he talks, Keaton displays superpowers that are intentionally left vague as to their foothold in reality.
Direction was very good
Acting was very good
Story was very good
Cinematography was excellent
Effects were very good
Bottom Line: An excellent and unexpectedly intelligent movie. Go see it.
4.5/5
