Reno
The In Kraut
Well, yeah, spose, sort of....it's not a interplanetary communication/travel film at its core though. I was hoping for more sci-fi, less emotion.
I thought the central idea was lovely and the shots of the other earth hanging in the sky were beautiful, but the film wasn't that well executed and it was a little dull in places. I got thatv the lead actresss was trying for "traumatised" but she seemed to sleepwalk through the film.
This 60s film has a similar concept and is more sci-fi, with rockets and stuff:
