Birdman.

Birdman director Alejandro G. Iñárritu originally conceived the film as a comedy filmed in a single shot set in a theatre following the character of Riggan Thomson, a faded actor famous for playing a superhero named Birdman in a film trilogy from 1989 to 1992. While the film used camera tricks and illusion to make Birdman seem like a two-hour-plus single take, it still involved several long shots that are incredibly difficult to film in a practical setting. According to Lubezki, most shots are around ten minutes in length, with the longest take around fifteen. Even a single one of these takes would be considered a daunting and possibly unnecessary task in a production. more »»
