Director Malik Bendjelloul said that he had run out of money while making the movie and had to film his remaining shots with his iPhone and the 8mm Vintage Camera app. The iPhone and app's performance were so impressive to Bendjelloul that he re-shot footage playing on his laptop screen with the app.
This isn't the first time directors have used iPhones to shoot films, but it's an important milestone that shows that footage shot with phones and apps are good enough to be recognized at the highest level and not distract from the overall quality of the film.
