This is an excellent first movie, containing young talented actors/actresses.
In one review it's said that this movie inspired/stolen by an Stephan King Novel and there is a point about the date of the movies.
First of all There is no contradictory about the dates of the movie. But back on those days (1999) because Cagan İrmak was not a well known director, this movie never made public attention. I'm not sure if this movie screened in theaters or only in festivals in 1999. But in 2007 or 2008 after Cagan İrmak become a popular director, the producer/firm which have the distribution rights of the movie decided to publish the movie again. I'm not sure if the movie was screened in theaters after this second publication but i'm sure that DVD's of this movie was published. As far as i know director Cagan İrmak was against this publication because so far he made popular movies in Turkish Cinema and didn't want an old movie of him to be used as a commercial project. So there is no suspicious situation about the dates of the movie.
Secondly about the inspiration from Stephan King Novel, the user used the story was Stolen from the novel. Inspiration and stealing a story are too far sides from each other and its a serious accusation to say a movies story is stolen from another story. I never read Stephen King's that novel so my comment could bu subjective but i can easily say that the story and plot of Bana Sans Dile can't be stolen from any story or book or movie because subject of an student taking his classmates hostage using a gun is not a original or unique concept. especially events like Columbine High School massacre could possibly be the inspiration of this movie. As i said the plot of the movie is not unique so its hard to say that its stolen from another novel.
