David Tennant Joins St Trinians II

Dr Who is about to turn nasty

It's detention time for David Tennant as he goes from Time Lord to House Master for St Trinians II: The Legend Of Fritton's Gold.

As if one installment wasn't bad enough, the girls in small uniforms are back, and they're ready for a spot of gold-digging. Searching for the hidden treasure of the legendary Fritton's Gold, the film will see Tennant sizing up to the girls as their arch-nemesis, the mysterious misogynist Pomfrey, part of a woman-hating secret society called AD1.

Also joining the cast will be Girls Aloud 'bombshell' Sarah Harding and softly spoken Ashes To Ashes WPC Monserrat Lombard. Returning for another term are Rupert Everett, Colin Firth, Gemma Arterton, Talulah Riley, Jodie Whittaker, Juno Temple, Tamsin Egerton, Celia Imrie and Fenella Woolgar.

The film begins principal photography today, for an eight week shoot at Ealing Studios.
