Many fans have also suggested the main man Sam Heughan himself may show up today although this has not been confirmed.

As previously reported by the Evening Times, a sign was first spotted outside Cumbernauld Glen in the Lanarkshire area last week, informing residents of filming for a fourth series of the hit show.

Shooting has been taking place since Friday, January 26 and also on Saturday, Monday, and today (Tuesday) between 8am and 7pm.
