Time Traveler

I saw this on YouTube last year when it first came out. I forgot about it and something reminded me about it again so I decided to post it. Has anyone seen this?
This man named George Clarke found a piece of footage from behind the scenes in Charlie Chaplins film 'The Circus'. The movie is from 1928. In this scene, it shows a large woman dressed n black and a hat covering her (or his?) face, holding what appears to be a cell phone. To everyone's knowledge there was no cell phones in the 1920's. If you look closely (and look at the scenes in slow motion) you can see this person is holding something to their ear and talking. George Clarke believes this is a time traveler. What do you think?? If you could travel to the past, what year would you pick?
