"A Man Of His Word" will see the Argentine pontiff respond to questions submitted from people around the world, with US production company Focus Features billing the film as "the first in which a Pope addresses the audience directly, discussing topics such as ecology, immigration, consumerism and social justice".
German director Wenders, who has been nominated for three Oscars including for his Cuban music documentary "Buena Vista Social Club", said Francis was "a living example of a man who stands for what he says".
"In our film, he speaks directly to the viewer, very candidly and spontaneously," Wenders said.
"Through the full cooperation of the Vatican, we were privileged to have several long audiences with Pope Francis."
The film features Vatican archive footage showing Francis on his trips around the world, as well as the interviews.
