Solaris (2002)

Remake of the 1972 Russian film from director Steven Soderbergh. This is a shorter version of the older film - by the 10-minute mark, the main character of Dr. Kelvin (George Clooney) is already on board the space station which orbits the mysterious planet of the title. He's an expert psychiatrist who had been requested to go there by one of the crew and by the corporation in charge of this station. Unfortunately, by the time Kelvin gets there, the one who requested his presence has already committed suicide. There are many other strange occurrences on this station, mostly involving the appearances of long dead people, but the first theory about this being the result of psychotropic drugs doesn't hold up.
