The flashbacks of Sister Clodagh's life prior to her becoming a nun were deleted from the original U.S prints of the film.
The closeups of Sister Ruth applying lipstick and wearing makeup were deleted from the original U.S. prints.
The 'Madness of Sister Ruth' (Kathleen Byron) with a classic scene of all-stops-out, sex-starved insanity was removed from the original U.S. version to avoid offending the Catholic Legion of Decency.
This scene was restored when the film was re-released in the U.S. in the 1980s.
