This film was released straight to DVD throughout most of the world, and was apparently filmed in Bulgaria. Dolph Lundgren did just five days of filming, Jean-Claude Van Damme did a whole twenty days of filming. The budget was clearly fairly modest.
If you start watching this film with low expectations, you should be pleasantly surprised. The opening sequence is one of the best that I have seen in an action film, reminiscent of Bond or a John Woo film.
The plot concerns terrorists who have kidnapped some people, while the bad guys and the good guys have brought back from the dead some Universal Soldiers. However you don't watch films like this for the plot. It is action pretty much all the way. Peter Hyams does the cinematography, his son does the direction. They clearly know how to make a low budget go a very long way. A striking cast, striking locations, striking camera angles, there is plenty going on to keep you engaged and distract you from the wholesale implausibility of the whole thing.
If there was any CGI or wire work, then it was not obvious.
The lack of budget did show in just how paltry the opposing armies were, and although the scenes with the universal soldiers felt believable, putting up some scaffolding and strip lights in an East European ironworks, does not make for a convincing facsimile of Chernobyl. They did manage to get a fair amount of screen time out of JCVD in the twenty days, and he is an engaging presence, Lundgren is genuinely creepy while he is on screen. The rest of the cast acquit themselves well, and as they are all fairly unknown you cannot predict who is going to make it to the end of the film. Though obviously if you are wearing a balaclava and waving a machine gun, you are unlikely to last terribly long in a film like this.
Finally rated as 18 for violence, this is brutal, but action fans should find it entertaining without being unduly gruesome.
