The Four Just Men, also known as The Secret Four, is a 1939 British thriller film directed by Walter Forde and starring Hugh Sinclair, Griffith Jones, Edward Chapman and Frank Lawton.

The Four Just Men was re-released in 1944 with an updated ending featuring newsreel of Winston Churchill and the Allied war effort as a fulfilment of the ideals of the Four.

The New York Times reviewer wrote, "Four Just Men, by Edgar Wallace, whatever it might have been, was probably not a work of literature, and therefore, on that charitable assumption, it is gently, rather than harshly, that one must deal with the British-made screen version, now on view at the Globe Theatre.

Like all pictures seeping over from England nowadays, it is more than a little infected with the virus propagandistus, but, over and above that common-carrier failing, it is a model of sheer incredibility crossed with what (carrying out the charity idea) we might designate as espionage melodrama".

But in all other respects it's a rollicking boys' own adventure, with some of the most fiendishly comic-book murders you will ever see... hugely entertaining sub-Hitchcockian antics".
