Wim Wenders’ 3D documentary “From Inside Out,” which has its world premiere at the Venice Film Festival on Sunday, examines the work of Pritzker Prize-winning architect Peter Zumthor, paying particular attention to the design and construction of the David Geffen Galleries of the Los Angeles County Museum of Art.

In the film, the result of a 14-year collaboration with the architect, Zumthor explains how he approaches the design of his buildings so that they are in harmony with their surroundings and serve the people who will use them.

Wenders first came across Zumthor’s work when the architect took part in a competition for a gallery building in Berlin, opposite the Neues Museum. “It looked splendid but wasn’t built,” Wenders explains.

Among those appearing in the film are filmmakers Ava DuVernay and Werner Herzog, actress Ever Anderson, singer-songwriter Sophie Hunger, visual artist Tarek Atoui, and actress and dancer Aoi Yamada, who also appeared in Wenders’ “Perfect Days.” Brad Pitt serves as executive producer on the film.

Variety submitted a series of questions to the director about the film, and publishes his written responses below:
