John Simm to Return?

A recent filming picture for Tennant's finale shows a man that looks like, and could be, John Simm walking by Bernard Cribbins.

If this was to be John Simm, he does look a bit different since he last appeared in the Series 3 finale.

Simm played the Master in the Utopia/The Sound of Drums/Last of The Timelords three-parter

You can view the picture here.

Please remember that this could not be John Simm, and he might not reprise his role for the Master.

What do you think of the picture?
