FILM 1545: WINGS OF DESIRE
TRIVIA: In the closing titles it says: "Dedicated to all the former angels, but especially to Yasujiro, François and Andrej." That refers to Yasujiro Ozu, François Truffaut and Andrej Tarkovsky.
All of the black & white sequences were shot through a one-of-a-kind filter made from a stocking that belonged to cinematographer Henri Alekan's grandmother.
Filming the actual Berlin Wall was prohibited, so a replica of the wall twice had to be built close to the original. The first fake wall warped in the rain because the contractor cheated the producers and built it from wood.
This movie was the basis for the American City of Angels (1998) movie with Meg Ryan and Nicolas Cage.
The photograph on the cover of the book that the old man opens in the library is "Young farmers" taken by August Sander.
