I finally got my hands on
Blindpassasjer, a norwegian science fiction-series from 1978. It was broadcasted in three episodes, each with a nice cliffhanger. It's reminds me a lot of those classic british TV-dramas from the seventies (for example Nigel Kneal), and has the same visual style and feeling. It's like Doctor Who - but a bit more stylish (in my personal opinion).
We follow the spaceship Marco Polo from it's journey from the planet Rossum - a farmer-based planet ruled by primitive robots. But something is of course strange with the planet, and that's something that will be revealed later in the series.
During deep sleep an unknown entity, a "biomat", sneeks aboard the ship and kills one of the crews, stuffs the person in the garbage disposer and takes it's identity. When the crew wakes up and discovers that someone is aboard the ship it's already to late. One of them is the "biomat"... an perfect replica of a human being... Now they have twenty hours to discover who it is, or else the spacestation Nexus will blow them up. Everything to stop infection...
It echoes of The Thing and Alien, but it's more of a whodunit set in space. The special effects are uneven, of course. Some of it looks great - especially the miniatures and the sets, but the visual effects and the graphics are very, very primitive. But I don't care of course, it's all about the story.
The cast is a few of norways best actors, and Björn Floberg is probably the most famous of them. Henny Moan, who plays "Leda", also starred in one of the biggest horror classics from Norway, the 1958 De Dødes tjern (aka The Lake of the Damned).
There's a few great twists and eerie sequences, one of my favorites is when one of the characters goes to an unknown spaceship that they found floating in space, and with a videokamera examin the ship and the dead bodies in there.
It's out on norwegian DVD, no subtitles though. But for collectors it's well worth picking up.
