Today's Throwback Thursday post is a collection of photos of David Tennant and his co star Christian Brassington on the set of the 2009 film St Trinians II: The Legend Of Fritton's Gold.

The film was a sequel to the 2007 film based on the 1950s/60s comedies set in a girls' boarding school. This time around, the mischief-making girls of St Trinian's are on the hunt for buried treasure after discovering that their headmistress Miss Fritton is the descendant of a famous pirate.
