He is one of the best known faces in television comedy, yet the long-suffering vicar of Walmington-On-Sea is in real life a Christian of deep conviction. Perfectly cast as the eccentric vicar, constantly tetchy at the invasion of his church hall by Captain Mainwaring and the elderly platoon, he appeared in "Dad's Army" throughout its nine-year run and also in many other television and stage dramas. Still in constant demand for public appearances, Frank takes an affectionate view behind the scenes of the series and the world of show business and reveals his personal journey through faith. 2018 will be the 50th anniversary of the television series "Dad's Army", with Frank one of just two original cast members still alive.
