one of the best movie ever and the idea of a double interpretation involve we all . would be prot a schizophrenic or an e. t. ( no doubt in my opinion and but let keep the question open . ) . kevin spacey and the big screen monster and play prot a it should be do . let not forget jeff bridge and his great psychiatric . lastly and a masterpiece that speak for itself . can keep our eye wide open from the beginning to the credit and our mind think even when the movie be over . if you still do not watch it and go right now . and again and again .
