Was shot in Irving, Tx off of the funds made from Pete's Dragon.

Filming was hidden to public. The project wasn't announced until months after filming had wrapped.

The pie scene was done with just one take. Rooney Mara said it was vegan chocolate flavored and tasted terrible.

A24 acquired the film before it even premiered at the 2017 Sundance Film Festival.

David Lowery, who both wrote and directed the film, characterized his idea to create a movie about a ghost as a primordial miasm in his brain, as he visioned a ghost exactly like the one that is presented in the movie. He believes that it is a very goofy image that is breaking from the norm in terms of how a story is told and the tools that are used for it.

The film reunites writer/director David Lowery with regular collaborator Casey Affleck, as well as Rooney Mara, both of whom starred in his feature Ain't Them Bodies Saints (2013).

In one scene the young Hispanic girl Yasmina plays on the piano a few bars of the Ode to Joy, from Beethoven's Ninth Symphony. In a later scene the Prognosticator speaks at length about this symphony, during which the film's musical score also begins to play part of this symphony.

When Rooney Mara writes the note to stick in the wall, she was instructed to write something of deep personal meaning to her, and not to share it with anyone. That note remained in the wall when the house was demolished. Since then, Mara claims she has forgotten what she wrote.

The pioneer girl hums the song 'I Get Overwhelmed' - the song Casey Affleck's character sings.

The neighbor's ghost is played by Kesha.
