Two American internet entrepreneurs and a couple of party girls find themselves up against a fiendish alien invader while taking time out in Moscow. After the population is literally reduced to ashes, the group embark on a perilous mission to cross the city - avoiding the invisible predators - to reach a submarine waiting in the Moskva River to rescue them. Emile Hirsch and Max Minghella play the unlikely lads who gets unexpected help from a renegade electrician and a Mad Max-style Muscovite street gang.
If a murderous alien invasion ever took place then you'd hope that bankers, estate agents and dot-com entrepreneurs would figure highly on their hit-list.
Unfortunately, irritating internet whizz-kids Sean (Hirsch) and Ben (Minghella) are among the only survivors when an extra-terrestrial force descends on Moscow, zinging the population into a pile of ash and sparks.
Hooking up with a pair of gap year party babes (Thirlby and Taylor), they strike off through the eerily deserted city along with the Russian wideboy who pinched their TripAdvisor-style web idea. Perhaps the entry should read 'don't go to Moscow'.
In novel fashion, their invisible unearthly foes announce their lethal proximity by setting off anything electrical from car alarms to streetlamps.
Yet the guys fight back, finding sanctuary with a renegade electrician who has put together a gun made from bits of microwave oven and a Moscow street gang whose leader has chain mail made out of lots of keys.
To engender a little sympathy it would help if the main characters were remotely likeable...but these two wideboys have all the charisma of a Soviet dossier on tractor productivity.
The dialogue is a seemingly unending collection of half-hearted one-liners penned by a scriptwriter with no apparent sense of humour.
Paltry saving graces include a desolately empty Moscow (perhaps the locals heard that Emile and Max were in town) and the occasional squirm when a wraith-like predator drifts down a street.
Other than that, it's an awkward re-hash of any number of superior movies ending in a risible liaison with a CGI submarine that would look unrealistic in an episode of Bagpuss.
Possibly one of the darkest hours you'll spend in a cinema this year.
