Ever wonder how "Birdman" director Alejandro González Iñárritu and cinematographer Emmanuel Lubezki got that one incredibly long continuous shot? Well, technically, they didn't.
The Academy Award-winning film starring Michael Keaton used very sophisticated edits to create that illusion. The editing technique was pioneered by director Alfred Hitchcock, and there's some wonderful visual perception science behind why it works.
YouTubers Frame by Frame made this fun video pointing out the hidden edits you may have missed.
An earlier viral video by Variety Artisans covered the same territory in a slightly different way. Watch that one below.
And here is the original "Birdman" trailer.
