I've had similar experiences. What happens is that you saw the film in the world of eternity, the astral plane, before such an event crystallized in the physical world.
Events in the astral plane, a world beyond time, can manifest physically after many years, since physical events unfold from actions in the internal planes.
I once saw, many years ago in the astral plane, a film promotion or sign board for a new movie: Indiana Jones and the Kingdom of the Crystal Skull. This happened before the film made its appearance in the physical world.
For thirty years I sought God. But when I looked carefully I found that in reality God was the seeker and I the sought. -Bayazid al-Bastami
