This wartime tale directed by Anthony Asquith confronts full-on the essential moral dilemma of the necessity to commit murder in the cause of war. It does not take place on a battlefield, but in the starker situation of a covert assassination of a man believed to be compromising the Resistance Movement in occupied Paris. The man chosen to kill the suspected person is played by the young actor Paul Massie, aged 26. It was his first credited screen role, and he does an excellent job. For some reason, this highly talented and promising young actor never achieved the prominence in his career which he would seem to have deserved. After 1973, he only worked four times (the last time in 1996), and he died in 2011. The other film for which he will be remembered is SAPPHIRE (1959, see my review). The most powerful performance in this film was delivered by Irene Worth, as the character Léonie. Massie is sent to Paris to kill the suspect man, and Worth is his contact, with whom some very tense scenes indeed transpire. Worth's embittered intensity is very convincing and deeply disturbing. Lillian Gish appears briefly early on in the film as Massie's mother, but it is not a significant part. Eddie Albert is very good as a commanding officer, and James Robertson Justice has immense gravitas and a suitably ominous quality as the man who trains Massie how to kill an individual quietly and quickly by taking off a pair of long socks and turning them into a murder weapon. Leslie French is superb as the unfortunate Marcel Lafitte, who is wrongly suspected of having betrayed the Resistance, whereas he is not only innocent but a gentle, caring soul who loves his family and his cat and would not hurt a fly. The film is based on a novel by the American author Donald Downes, another of whose novels was filmed as THE PIGEON THAT TOOK ROME (1962). This film starts very slowly because Asquith and his writers are so keen to make their moral point that they dwell on the minutiae of Massie's recruitment and training to carry out his assignment. Today that would be sketched in a couple of minutes, but in this film it takes a long time. Once the action gets going, the film becomes very tense indeed, and finally it becomes very grim, as we face the moral dilemma. Asquith was clearly determined to make this film in this way because he was trying to examine the dilemma and drive home its insolubility. In a sense, we could call this fifties film a true existentialist film, in keeping with the prevailing philosophy of that Heidiggerian decade. It explores 'what a man must do' and the 'nausea' following his actions. It bears some resemblance to the concerns of André Malraux, who in the novel MAN'S FATE contemptuously says that anyone who has not killed someone face to face is 'a virgin'. One wonders if Jean-Paul Sartre visited the set, steeped in nausea, and whispered existential doubts into the ear of the director. Much of it is filmed on location in Paris, and there are some very fine and atmospheric location shots. This film evidently meant a great deal to Anthony Asquith, who had a social conscience which he wore somewhat on his sleeve, and we owe him the consideration of listening to his message, which after all is a very worrying one, even if we find it deeply disquieting.
