It came on t.v. late at night several years ago. It centered around a doomsday cult who thought the world was going to end so they rounded people up to put them to sleep so they could be transported to a better place and not suffer when the world ended. One man didn’t believe them and tried to save his child but once he did the world ended like they said it would.
Any chance it is
The movie is about aliens and the end of the world, and the main character, Nicolas Cage, manages to save his child with the aliens’ help at the end of the movie.
