Russia has picked four people to serve as nonprofessional crew members and actors in what is planned to be the first movie shot in outer space, Russia's Roscosmos space agency said on Thursday.

Some of them are scheduled to be launched on a Soyuz MS-19 craft on October 5 to be delivered to the International Space Station (ISS), which orbits Earth at an altitude of around 354 km, according to Roscosmos and NASA.

"Among other things, they will have to take centrifuge tests, vibration stand tests, perform introductory and training flights on a zero-gravity plane, undergo parachute training," Roscosmos said.

The film has the working title of "Challenge," and the four will begin training for space flight by the end of this month, the agency said.

After a medical screening and as a cast for the drama, Russia has picked 36-year-old actor Yulia Peresild and actor and director Klim Shipenko, 37, to be included in the main crew.

Actor Alena Mordovina, 33, and camera director Alexei Dudin, 40, were nominated for a reserve crew.

In October 2020, Russia sent the last crew carrying a U.S. member to the ISS, marking an end to a long dependency as the United States revives its own crew launch capability in an effort to drive down the cost of sending astronauts to space.
