I just saw this flick on DVD. I generally agree with Jessewillis' comments, and won't repeat them here, but would like to add a few more comments regarding some special features that to me added to the value of this movie.
First, POW escape films in general, for Americans, tend to have such a very different geographical scope. An escape from a German prison in WWII, for example, will feature (say) American or British soldiers who seek to escape from Stalag X and seek repatriation across hundreds of miles to get back to (typically) Britain. In contrast, this movie, filmed on location in Israel, gives us a very different sense of geography and terrain. The notorious prison is within 20 or 30 miles (I can't recall which) from the Israeli border. It's a rough escape trek, but it's not far, and when the escapees suddenly spot the sea, and know they've made it, we get such a strong sense of the closeness and proximity of things in Israel and Palestine. Likewise, the dry, sparse, craggy terrain around the prison is (of course) the same as the dry, sparse, craggy terrain just over the border in Israel. So the escapees aren't getting that far away, and aren't spotting the White Cliffs of Dover on the other side of the Manche, but the sea that is itself the other side of Israel. The closeness of things comes across to me very, very strongly in this film, and gives a very different flavor to an escape film from those I'm used to.
Second, there's a strong sense of time and antiquity side-by-side with the vivid here-and-now. The prison is located within strong but crumbling walls that we are told date back either to the time of Christ or the time of Mohammed. This dry, rocky, hard earth stretched out under wide open skies is, we sense, not so much different from the land through the centuries. And when Valentino dies during the Escape, just before the escapees reach Israel, Beno (I think it was?) states strongly that they will somehow bear the body back to Israel, for he will be buried in Israel. We get a strong sense of the "eretz", the land that has been there almost from before time, and which remains the "eretz" today.
Third, there's a strong sense of ethno-religious distinctions that in the West we're just not really familiar with in our Escape movies. The Germans and the Americans and the English actually all share a common ethno-religious heritage; it is national differences that are in play in the conflicts in WWII and the like. In contrast, while national identity is a part of this Israeli film, so is the ethnic and the religious identity of the parties. I've already noted that time and dates are regarded in religious history terms: the fort dates to the time of Christ or the time of Mohammed. Religious allusions abound throughout. So do conjoined ethnic allusions. The Arabs are Muslim; the Israelis are Jewish. This certainly makes for some potentially treacherous ground in film-making, since we have all of the Arabs being the Bad Guys and all of the Israeli's being the Good Guys. But there are some interesting nuances that would be more familiar in the Middle East perhaps than in America: hence a guard helps Eli, and we discover that the guard is not Arab / Muslim of a "conventional" kind, anyway, but he is Druze. The Druze are a distinctive ethno-religious community which often found common interest with the Israelis in southern Lebanon and in Golan. But again, the point is that adding strong ethno-religious distinctions to the national distinctions involved in the conflict setting of this movie really adds a different "flavor" to this POW escape movie.
All in all, I liked this movie, not only because it makes for a great B-movie of the POW escape / action genre, but also because it offers such a strong and distinctive experiential flavor that is "different" for me, anyway, as a resident of the continental USA.
This is really good, solid POW flick with delightfully exceptional experiential features & flavors, and if you like this kind of thing, as I certainly do, I strongly recommend this movie to your viewing pleasure.
