Disastrous Casting Averted .....
Producers wanted Ann Todd for the role of Kathleen,in hopes of reigniting the box office, as her previous pairing with James Mason, THE SEVENTH VEIL, had done.Filming began, when suddenly Todd was unavaiable. Carol Reed had to scramble for an actress, and asked some of the Abbey Players if they knew anyone who could play Kathleen Sulllivan. Dan O'Herlihy or Cyril Cusack suggested Kathleen Ryan, with whom they had just done a play in Dublin.
Can you imagine Ann Todd as Kathleen? It would have sunk the movie completely. Nothing against Todd, who was perfectly cast in THE SEVENTH VEIL, but she could not have been a credible Kathleen.
