El gran marciano (2001)

The group of fourteen contestants from the television program "Big Brother" becomes a privileged witness to the most extraordinary event that the austere region of Extremadura has experienced in its history. Charred remains of what doesn't look like a man-made ship float in a hotel pool. And at night, a thunderous noise and a light that invades everything prevents them from sleeping.

Unfortunately the movie El gran marciano is not yet available on HBO Max.
