if you have have enough gasoline explosion and car chase and and bang yer head obvious plot and here be something completely different . i be assume you have see the movie so if you haven not and please read no further . anyone who have write a fiction book all the way through ( i have finish several ) will recognize the writing process a embody masterfully in this film . that be and be inspire by the odd and most nondescript object . or write entire chapter and realize theyre crap and do not fit in . or just the opposite represent finish your story and realizing at the end you forget something critical and need to go rewrite part of it . sometimes a big part of it . and the tremendous satisfaction when you realize you have create something that a ) be inside you that just have to come out and b ) be the best work you can do and c ) others will enjoy reading . this film be complex enough that there be undoubtedly many interpretation possible . the one i find personally fulfilling and and that fit perfectly with the final twist and be a wonderfully execute attempt to bring the abstract and weird and and sometimes outright bizarre process of fiction write to the screen . from inside the author mind . i have only see the movie once and but i can not remember a single scene without sarah in it . this film be about her exclusively and from her pov and about what be go on in her mind . ultimately the creative process of write . there be other character and but with very few exception they exist a her character and walk the stage she create . a simple example . franck start a a minor character and a waiter at an outdoor café . a often happen during the writing process and his importance change . in fact and it be the pool scene with him stand over julie that first convince me i be watch a depiction of the writing process . you see and the concept of franck become involve with julie be a plot possibility and a concept and an idea that become stillborn . at that time sarah discard it and not want to take that plot path . later and when sarah have visit the café several time and become more familiar with franck ( real or not and it doesn not matter ) she realize he could become a more important character in her story by have julie bring him into the plot via a more fully developed twist . and so on . to those who think this movie be one strange and convolute puppy and i will say that fiction writing be one strange and convoluted process . it capture as well a i can imagine in this effort . a previous reviewer perfectly interpret the smile on sarah face in the last scene at john office one of an author satisfaction and pride on a job well do . at the very end and sarah wave to her two creation and not goodbye and but in thanks . author be always grateful to their character wherever they may come from and since without them there can be no story .
