A brilliant film that helped define a genre

Great movie. Not sure what people expected but I found it highly entertaining.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.

By the time the dramatic fireworks start popping off, each one feels earned.

This is a very fine and interesting film noir — among the better films of post-war British cinema. The story with twin trapeze artists might be a bit far-fetched in some aspects, but the opening of the film is brilliant, as is the ending. The photography is in beautiful dark tones and the music accompanying the trapeze acts is excellent. Herbert Lom is convincing in the role of both twins. I think the merit of his subtle performance lies above all in not exaggerating too much the difference in character between the two twins. Extreme characterization is normally a much easier option for an actor or actress when one thinks of other famous stars playing twins, such as Bettie Davis, who did this twice in "Stolen Life" and "Dead Ringer", or Olivia de Havilland in "The Dark Mirror". This is an excellent British film noir which deserves to be much better-known. Apart from this, I have not seen any more films by Alfred Travers, who seems to be a totally forgotten director. Astonishingly, hardly anything seems to be known about his life and career (apart from the titles of the films he directed), not even the date of his death. This must surely have happened, as the only scant detail available about this director is that he was born in 1906, in Constantinople.

I watched this one and was dead sure I had seen it before. Pretty sure at one hundred percent. Same atmosphere among a circus little world, starring Herbert Lom in both films, and also a crime drama topic, with our lead as the bad guy.The other film was actually DARK TOWER, shot in 1943, where Lom played a sort of evil hypnotist who wanted a young trapezist woman to be under his bad influence. A very good noir from UK too. And no user seem to have seen both. Or maybe they did not notice that further.So, I do. There are here two very similar features. And, I repeat, with the same actor playing very similar characters. Worth watching for both of them.

"Dual Alibi" is a good crime story with a twist; the protagonist(s) are identical twins. It appears to be a British attempt at the noir genre and the mood is dark and humorless, reminiscent of the 'Twilight Zone' TV show.As I said, the story is good and is somewhat predictable throughout. Herbert Lom stars in the dual role, a high-wire circus act from the continent. One of the twins gets snookered by a con-man agent and his girlfriend and there is a falling-out, with predictable results. I was not as enthralled with the picture as most other reviewers but I appreciated the irony of the plot and the acting of Lom, who carries the picture.Nice work turned in by the two chiselers, Terence De Marney and Phyllis Dixey, who has only 2 films to her credit. This movie is so old I was unable to readily spot Sebastian Cabot, who in hindsight looked very young and slimmer than I remembered. He had a speaking part which lasted a few minutes, plenty of time to recognize him. If you are interested in "Dual Alibi" you should know that it is hard to come by nowadays - and it's good, but not great, in my estimation.

This was a fine example of a British film, well acted and directed, an excellent storyline and no slip ups or confusion as sometimes arises in plots like this. Herbert Lom gives a spellbinding performance as the twins, and the rest of the cast are marvellous too. Everyone gives 100% and we enjoyed it very much. It should have got some awards. Please do watch it, if you get the chance. you wont be disappointed. A fine cast of actors doing a brilliant job with a first class director. Superb. I had not been aware of this director before and as he wrote the script too, (oh yes, I forgot to say excellent script) he has excelled himself. Why no proper recognition ? I had not even heard of this film before. It was shown at a quarter to three in the morning! The photography was well done and the matching was excellent too. This film should be acknowledged as a classic British film.
