The story behind the film
The Boultings made an indomitable team, and when they decided to pursue the rights to Graham Greene’s novel, there was little doubt they would get them. The then owners, who included Terence Rattigan, agreed to sell, but Rattigan – whose own plays have been turned into fantastic cinema over the years – had a proviso: he wanted to write the script. The brothers agreed, but were unhappy – they had wanted Greene to do it himself. In the end, they got their wish, and Rattigan and Greene (who had heavily doctored Rattigan’s original treatment) shared an on-screen writing credit.
