He should get credit for arranging it.
He didn't compose anything, except some stupid strings and beats added to the original pieces.
Music Composer: Jeff Dana? Should be Akira. Jeff Dana is just a scorer isn't he?
True Jeff Danna didnt compose almost anything for the movie, but if you read the credits at the end it says clearly "Music by Jeff Danna" it doesnt says he compose it. Also some of the music from the games is credited later and giving the credit to Akira Yamaoka. Jeff Danna made interesting mixes to the music, not stupid, as he is a more than capable composer, and IÂ´m sure if Christophe Gans let him, he would have made a memorable score (not that the movieÂ´s actual music is bad or anything, I love it). And the scorer I think is the same guy who is a composer
