Philip will play Mr Gunn the "lothario" gym teacher.
Catherine Tate also stars as Miss Postern, the French teacher and Francis de la Tour will play Ms Baron, the no-nonsense, plain-speaking headmistress of Greybridge School. Joanna Scanlan will play Mrs Klebb, the nosey and interfering drama teacher, while Steve Speirs plays Mr Barber, the pessimistic geography teacher who’s counting down the days until he can retire. Finally, Daniel Rigby will play Mr Martin, the mod-like music teacher who desperately wants to be mates with the kids and still clings to his dream of becoming a rock star.
Filming will commence within the next few weeks in the Greater London area.
