Strange Attractor's Mark Pilkington pointed me toward this enticing taste of Lunnaya Raduga (Ð›ÑƒÐ½Ð½Ð°Ñ Ñ€Ð°Ð´ÑƒÐ³Ð°), a 1984 Russian science fiction that looks terrific! Here's a description from AllMovie:
In this watchable sci fi story based on a novel by Sergei Pavlov, the time is the 21st century, and the space security organization has a dangerous situation on its hands -- it seems four individuals from outer space have the ability to change form and to affect radio transmissions and magnetic fields. Their powers could threaten governments on earth and seem to derive from an unusual accident on one of the moons of Uranus shortly after four astronauts landed. Now the space police have to bring this potentially disastrous situation under control.
