Sphere (1998)

Sphere opens on the most seductive image in USO folklore: a team of specialists rushed to the floor of the Pacific to examine a huge, apparently non-human vessel that has lain on the seabed for centuries. Levinson quickly upends the expectation — the "spacecraft" turns out to be a human ship from our own future, and the truly alien object is a glowing golden sphere buried inside it. Anyone who enters the sphere can make thoughts real, so their fears turn lethal. Adapted from Michael Crichton's 1987 novel^[1], the film relocates first contact from the sky to the abyss and rewrites the alien threat as a projection of the human mind.
