i be czech and soldier ( not only pilot ) who escape czechoslovakia after nazi invasion in 1939 and fight against them abroad be true hero and brave men in our history for me . this movie from director of academy award winner kolya ( 1996 ) be a tribute to these men . it first big screen movie about czechoslovak wwii soldier since nebesti jezdci ( 1968 ) . i think dark blue world be a good movie good acting and good special effect and nice music etc . movie be half in english and some actor be briton . but great thing about this movie be it pure existence . it great chance to show people all around the world ( and to many people in czech republic too . ) that czechoslovak role in wwii be not only a occupied country but a an active member of allied campaign . leading character be old and wise frantisek and young karel . they escape together from czechoslovakia and they be fly in the same squadron and they fell in love with the same woman . maybe it a cliché but fortunately this storyline be not so aggressive and be in good balance with other scene ( include great dogfight ) . i do not want to compare dark blue world with pearl harbor and someone will like ph more and someone will like dbw . but if you like happy end and dbw be not for you . so and i think it very good movie for everyone who like this type of story and very good movie who want to get to know something about this chapter of czechoslovak history . btw and main theme dark blue world be from czech 30 and 40 composer jaroslav jezek . he write this theme when he lose his eye .
