12 Movies That Made You Work Out The Answer Yourself

The Question: What happened to Riggan (Michael Keaton) after he climbed onto the ledge of his hospital room?

There are a bunch of theories here, so let's run them down. Some believe Riggan died from shooting himself on stage and the film's final scenes are nothing more than his dying hallucination, which would explain why it's almost comically idyllic.

Conversely, there's the rather out-there theory that Riggan can actually fly, which at least makes a little more sense as we see his daughter Sam (Emma Stone) looking up into the sky after clearly not seeing his corpse at the foot of the hospital.

Perhaps the most plausible suggestion is that Riggan really did jump out the window and die, and Sam's reaction is merely her entering a fantasy world where her father flies away rather than splats violently on the pavement below.

Unlike Kubrick, Alejandro G. Iñárritu has refused to offer his own interpretation of the finale, and given the film's generally surreal quality, it's hard to fully commit to one defining theory.
