Imagine Charles Dickens had to make a bit of extra money by writing B-movies in Hollywood and you might get close to imagining this haunting, wonderful film. It fuses the best traditions of film noir with a very British atmosphere: a cast of character actors playing vividly drawn and desperate people.

There’s a mournful tone to the whole film, like a boat’s siren drifting across a foggy Thames. All the characters seem to be reaching for their hearts desire, wanting to believe in a dream of a better tomorrow, in something that’s real and true for them. But they rip into each other trying to get there. That gives the film a poignant, tragic trajectory.

A compelling central performance by Richard Widmark as Harry Fabian, a man with flair and drive and an infectious hope, but a man who lacks something like the moral fibre to be honest. A man always looking for a shortcut. A nearly-great man, an almost classically tragic figure. Googie Withers is a revelation as Helen, a woman who seems cynical but has hopes and dreams just like Fabian (just like all our characters).

So much I haven’t even mentioned, the sweaty muscular wrestling scenes are are action scenes of the best kind, in that they drive and skew the plot as well as holding our attention. So many good performances. And a film that speaks to our hopes and our flaws and the tragic spaces between the two.

Any Londoner or person who loves the atmosphere of that city should check it out too, some lovely old footage of Trafalgar Square and Picadilly.
