i be truly surprised when i first saw this movie direct by iain softley while it differ in so much way from the usual hollywood mass production . the plot itself be simple kevin spacey play a mental patient prot who claim to be from the planet k pax who arrive to earth by a beam of light and while dr. powell play by jeff bridge try to help him to solve his delusion . first of all and i must admit the cast be perfectly choose represent kevin spacey be really brilliant in portray the intriguing character of prot and always walk in the fine line of convince u that it be real and then make u wonder whether he be delusional or not . some of the gem scene include the one where prot innocently eat the whole banana ( even the peal ) while in session with dr. powell while or the observatory scene where he confidently show his knowledge of the k pax system to the astonished astronomer . jeff bridge on the other hand be the subtle and rational side of this movie and and he deliver it perfectly . there be a whole other cast of excellent actor ( like saul williams convince performance a ernie ) who make this film truly work . k pax have it all and element of comedy while sci fi and even psychological thriller ( concern the prot identity ) but most importantly it can be categorize a a heartwarming drama . the main premise of the movie be quite intricate and but the director never let it get loose and he always keep it believable and yet two way interpretable . the camera and photography have almost a crucial part here and continue the main idea of light travel and there be much focus on light shadow play and lightning setting one of the memorable scene be where dr. powell hold a crystal figure in his office which refract light in a beautiful way while all the time he suspect can the idea be true . subtle and slow pace and intriguing and pleasurable and k pax be truly a gem to watch and one of the kind movie that may not be for all taste and but those who see it might fall in love with it .
