Charlie Chaplin’s status as an extraordinary talent was already known, but a new web video would have him be a visionary too.
A video from a bonus feature of the DVD to Chaplin’s 1928 film The Circus shows a woman talking into something she is holding up to her ear.
It appears to be a mobile phone, although they were not invented until the 1970s.
It is likely the actor is holding a hearing aid, but that has not stopped the video from amassing more than two million views on YouTube.
The clip was discovered and uploaded by Belfast film-maker George Clarke. He claimed the person was a time-traveller and that “you just can’t explain it”.
