It's the work of Simon Smith, a director and producer.
Simon tells BuzzFeed: "I’d always been amazed when people used this technique for still photos, and knew that it would be fascinating to see it in film, but no-one seemed to have done it before."

Simon searched out a bunch of archive DVDs from a film library, and came across "Wonderful London."
He says: "It's a collection of 20 shorts, each of around 10 minutes, by Parkinson and Miller, two documentary film makers from the 1920s."

Simon separated the films into a set of stills, and loaded them onto his phone.
He then went hunting for the places every weekend. "Once I found the location, I’d then move around with the camera, trying hard to match the angle, and small artefacts like columns or railings that might match," he says.
