A rare bright spot in a benighted genre, this British POW drama avoids familiarity not only by avoiding stiff upper lip and grey morality in favour of wit, tension and Hollywood stereotype, but also by a clever use of the metaphors of theatre. Most British war films parade their stifling docudrama-style 'realism'; this is often an excuse for imaginative paucity. 'Danger Within' uses the idea of play to question some of the received myths about the British Second World War.

Part of the novelty lies in its North Italian setting - we're so used to nefarious Nazis and brutal Japanese. Not that it makes much difference - the main villain, Capitano Benucci, is a Nazi-trained sadist, who imagines he's suavity incarnate with his sophisticated cigars, laidback walk, time goatie, and clipped, ironical speech. But the blanching sun makes a nice change, giving a parched, sandy feel, and the notorious stereotype of Italian incompetence makes the various plot points believable.

What makes this narrative absorbing is not the usual will-they-or-won't-they escape plot, but a kind of detective story. No matter how ingenious the efforts of the escape committee - and there is a brilliant one here involving sewers, light-switches, misplaced cigarettes and rugby posts- there is always the same welcoming committee of armed fascists ready to mow them down. It's clear there's an informer, but who?

The obvious culprit is a shifty-looking Greek. This is the film's first daring piece of iconoclasm. There is a lot of anti-Italian racism throughout, but that can be attributed to understandable wartime emotionalism, where contempt for what Fascism stands for is expressed in xenophobia. But the Greek's only obvious credentials for being an informer is the fact of being a Greek, a little small, sweaty, oily, you know, naturally sneaky. When his name is called at roll-call, a wit hurls a dead rat at the officer; we remember Nazi anti-Semitic propaganda that used similar analogies.

This is a strangely unideological war these men are fighting - there is no rhetoric about liberty and democracy; this is a prison film in which the criminals, all professionals, want to escape. Everything centres on the job in hand, with loyalty vouchsafed for anyone who agrees. This lack of sentimentality is refreshing an a genre stuffed with secular piety.

Even better is the working of the theatrical metaphors. The brilliant opening scene features a prisoner disguised as the commandant - their fatal meeting creates a mirror effect that echoes in the following narrative about, not only duplicity, but also people who don't seem to be what they are, including old fops who turn out to be very brave men. Of course, this is a situation where the Law are murderous criminals, and the prisoners are democratic saviours, ambiguous enough in itself. It creates a world where you don't know who to trust, especially dangerous in a situation where loyalty and trust need to be givens. This idea of acting and pretending (extending to the Capitano) culminates in the attempted escape during 'Hamlet', with the immortal Dennis Price in a mop wig as the Prince. It's a shame they couldn't have picked a more apposite play - King Lear, perhaps? - or worked it in better, with a play-within-a-play scene, for instance, to reveal the murderer. But that would have been silly, contrived, arty, and no British war film would ever be that. Michael Wilding is a bizarre sight in this testosterone heavy atmosphere; even more surprising is how excellent he is with his old queen patter and reserves of steel.

There's something about POW escape dramas, you rarely get a poor one. Firstly, unusual to see one set in an Italian camp. I'm not sure the harsh reality of POW camps were put across here, but that's not necessarily what the movie was trying to do. What it does have is an interesting script that moves along at a healthy pace. this is helped by a top notch cast who are all utterly believable. There are definite comedy moments but they don't detract at all from the action. This film was over in what seemed like no time & I would watch it again in a heartbeat. Two minor quibbles. I thought the informant was revealed a shade too early for me and I never felt that his motivation was sufficiently explored. Great, Boys own stuff.

DANGER WITHIN is another WW2 flick about British soldiers trying to escape from a POW camp; this time around the setting is Italy rather than Germany or North Africa. It's a familiar enough effort that proves worth a watch thanks to the exemplary ensemble cast and the emphasis on the lean plot, which is always on escape and escape methods rather than adding in any extraneous material whatsoever. The hunt-the-traitor sub-plot is a nice addition too. Cast-wise, you get typical character work from Richard Attenborough and hard-headed heroism from Richard Todd; others like Bernard Lee, Dennis Price and Terence Alexander add tot the ambience. It's not a genre classic, but watchable if you like this stuff.
