Speculators believe it to be either Tom Hanks or Bill Murray.
They believe it to definitely be Bill Murray because Tom Hanks was ‘almost certainly in New York’ when the photo was taken (the photograph’s uploader claims it was taken in Scotland).
In the real world, Tom Hanks recently hosted Saturday Night Live, helping Alec Baldwin mock Presidential candidates Donald Trump and Hilary Clinton.
People and US Weekly both also concluded the photo shows Bill Murray.
