Petlya Oriona aka
Orions Loop is another film from the Soviet Union, as it was once known.
From IMDB, because I've never had the pleasure....
"A strange phenomenon has been noticed on the outskirts of our Solar system that quickly approaches the Earth. It's called "Orion's Loop." A spaceship with a crew of people and androids identical to them is sent to intercept the anomaly. But strange events start happening as the spaceship approaches the mysterious loop."
Thanks again to Tim, for the pointer
