Continuity Errors as Design
Breaking the usual rules that keep space and time consistent between shots, on purpose. The mismatches tell you the film's reality or a character's view of it can't be trusted.
How this film uses it
The famous 'single-take' look is really a series of shots joined so you can't see the joins. The cuts are hidden in dark frames and behind passing objects. The seams are real. Nevertheless, time seems to run without a break, and that shows you how Riggan can't escape his own performance.
Where to see it
Riggan leaving the theater. The camera follows him from backstage through the theater and into the streets of New York in what looks like a single continuous take.
