So Prot was really a ? ...... (Spoilers)
Just finished watching this .The movie has all the ingredients of getting a 10/10 .Really fantastic job by both the actors (Jeff Bridges steals the show from Spacey in my opinion) .... a highly refreshing story about so called 'monotonous lives' we live as humans ignoring true happiness(like watching a blue jay in the middle of the day, a scene which really lifts the movie nicely) and our families .... BUT ... what lacks is that in the end the movie doesn't quite hold up its mark because of overly ,almost intentionally, trying to be AMBIGUOUS ...
up until the end its almost certain that prot is an alien because :
1. correctly describes the dynamics of a planet in a constellation which has been discovered only recently .Well he could be brainy and savant in astronomy(which already is almost impossible for a knocker in a slaughter house) as Jeff's character says but still he couldn't possibly be knowing this much about a planet whose existence is still in questions among the leading astrophysicists of the country.
2. doesn't respond to 300 mg thorazine
3. detects UV light that is impossible for a human being
4. Bess's disappearance in the end (and leaving her shoes behind which she definitely would have needed if she were to escape from the hospital)
5. banana CHOMP CHOMP in the beginning ....
HOWEVER there are various interchange of dialogues between prot and Dr. Mark which (figuratively) try to make us believe of him being an human....
1. prot saying that on K-PAX they don't have families and when asked by Rachel if he has a family he becomes a bit sad and says no ....both the instances implying the loss of family he(or Robert Porter if prot's not Robert) witnessed in life
2. prot telling how pregnancy is a painful thing on K-PAX ... during hypnosis prot says that pete (or robert porter) called him only when there's a problem .... and he once called him during his girlfriend's pregnancy and Mark saying that "does he blame her for this" ..... implying his girlfriend's pregnancy was some kind of a problem .....
3. prot becoming violent hearing the lawn sprinkler scene .... if he was just an alien and had taken over robert's body when he was going to kill himself in the river then he couldn't have known about robert seeing the lawn sprinkler after the horrid incident ....
4 . prot showing human emotions ...... extreme human emotions like fear and anxiety during hypnosis but being almost normal afterwards not knowing anything about the session .... a common thing observed in psychotic patients ...
5. prot saying there's no law or government needed in his world (K-PAX) .... this almost relates to the fact that his wife and children were killed by a lunatic criminal on loose which he probably thinks was a mistake of police(law) and so he took laws into his own hands(no need for law or government in his world)by killing the guy who killed his family......
6. the fact that 'prot' is jumbled form of 'port' from Robert [PORT]er ..... lol
So what does these things mean?? ... what exactly was prot ?? .... human or alien ????
