To celebrate that it's 2 years today since David Tennant's first preview performance of Hamlet in Stratford-Upon-Avon, the David Tennant Treat 4 Today today are two videos of him signing outside the stage door after performances.
Unfortunately I couldn't find any from Thursday 24th July but these two are both interesting if you enjoy listening to his interaction with fans.
In this first video somebody takes him aback by a comment they make.
In this second video I mainly included it as it's daylight so easier to see him. It's also quite long and you can hear a lot of what he says.
Just watch where the photographer aims her camera for a few seconds at the start of the clip!
