K-PAX
Gene Brewer
 A white male is picked up by the New York Police after being found bending over the victim of a mugging at Grand Central Terminal in midtown Manhattan. After having responded to the police questions with somewhat strange answers, he is transferred to Bellevue Hospital for evaluation. Although not physically ill, he is found to harbour a strange delusion: That he is from a planet called K-PAX in the constellation of Lyra. The patient, who calls himself "prot" (intentionally lower-case to reflect the insignificance of an individual life form in the universe), is eventually transferred to the Manhattan Psychiatric Institute (MPI), where he becomes the patient of Dr. Gene Brewer. Dr. Brewer, with the help of a journalist named Giselle, discovers that prot may simply be an alter ego (the result of Multiple Personality Disorder) of Robert Porter, whose life has been devastated by the murder of his wife and child and his subsequent killing of the perpetrator. When prot returns to his own planet, Robert Porter is left in a catatonic state. However, Bess (another patient prot had promised to take with him) disappears along with a box of souvenirs prot has been collecting. Prot promises to return in "about five of your years".
