The greatest directors are entitled to the occasional misfire and this would appear to be one of David Lean's. He was persuaded to do it by his wife Ann Todd who had played the part of alleged poisoner Madeleine Smith on stage a few years earlier. Ironically nothing of the play would remain and the film would become an original screenplay. Difficult to put ones finger on why 'nothing seemed to fit', to use Lean's own words. Even allowing for Ann Todd's customary 'temperament' this was by all accounts a far from happy experience and it certainly shows.
I think that Todd is excellent in the role and her final, enigmatic look to the camera after the jury has found the charges against her 'not proven' is masterful. Ivan Desny is very good as the vain social climber but it is difficult to warm to him so that his demise fails to excite our sympathy. Apparently Gerard Philipe was considered for the role. What a tantalising prospect! Notable performances by Leslie Banks as her unbending father and by Andre Morell as the defending counsel in the stupendous trial scenes whose oratory and impassioned pleas put sufficient doubts in the jurors' minds to enable Madeleine to escape the executioner. Norman Wooland is okay as faithful Mr. Minnoch but as an actor lacks that certain 'something'. This is by no means a 'bad' film and there are very effective moments but it simply lacks that elusive and magic alchemy by which everything comes together. Lean put the blame fairly and squarely on the writing. The film was both a critical and commercial failure and Lean was not to be so harshly judged until 'Ryan's Daughter' twenty years later.
