Basically it’s an older movie that shows a perfect heaven-like place where unborn children live. The place had a sort of Greek architecture, and the characters all wore robes. When the ones chosen to be born were sent away, they sailed away on something resembling a Viking boat. A man would come and read their names off a scroll to be sent to earth. Siblings would be sent together. I remember a teenage couple being in love, but being heartbroken when the boy was chosen to be born before her. I don’t know if the entire plot of the movie was this scene I recall, or if it was just a sort of subplot. As a kid I watched this movie multiple times, and cannot find it!
That sounds like the Heaven scene in the Shirley Temple movie “The Blue Bird.” Shirley and her brother visit Heaven and see almost exactly what you describe.
