Visible crew/equipment: After Riggan ran across Times Square in his underwear and comes into the theatre's entrance, the shot suddenly turns left towards the ticket office, on whose golden shelf the cameraman's legs are reflected. (01:15:04)
Factual error: The film makes use of a real Broadway theater, the St. James, which is on West 44th St. When they leave the stage door, the actors are next to the Edison Hotel, which is on 47th St.
Continuity mistake: When Michael Keaton goes to his dressing room following the light accident, the note on the flowers changes. It first reads: "They didn't have the whatever you wanted." After he removes his headpiece, the note reads: "THEy didn't have whatever you wanted - SAM."
