I'm not sure how to describe this bizarre, but beautiful movie.

First, it's long. Just one minute under three hours. And it's not exactly fast-paced either. If sci-fi for you means action, spaceships and interplanetary intrigue, give this one a miss. In fact, although the cover describes it as "The cult BBC Science Fiction film", I'd hesitate to call it science fiction; indeed, I'd hesitate to label it anything at all.

And it's definitely flawed. The dialogue is riddled with melodrama and pretentious poetry; the camera-work sophomoric, and the editing clumsy. And yet the effect shines through: the movie has an eerie, otherworldly quality, where trivial details (such as an old lady glaring at a noisy conversation in a library) seem to take on ominous significance.

And so, if you have the patience, you'll get sucked in to this movie. It's mysterious, and beautiful. But don't expect to come out satisfied. Although there is a plot, it is far from clear. The story moves from one surreal incident to another, each connected but seldom shedding any light on its predecessor; even at the end, when it appears that our protagonists have triumphed, it's far from clear what exactly they've triumphed over, and most loose ends are left firmly untied.

Hywel Bennett does a fine job as as the somewhat petulant author caught up in a situation that might have been co-written by Kafka and Philip K Dick. Dinah Stabb perhaps succumbs a little to her melodramatic script; Dan O'Herlihy brings an artistic gravitas to his role. A cameo from a very young Daniel Day-Lewis, and a supporting role by Sting, add a bit of celebrity interest.

Overall, Artemis '81 reminded me more than anything of Twin Peaks (which was made nearly a decade later, and, curiously, also featured Dan O'Herlihy) - the same sense of explanation hidden just around the corner, and another reality just half-glimpsed and poorly understood. I don't think everyone will enjoy this movie, but I certainly did.
