stick robert deniro in your movie almost assures you good review . stick sean connery only increase that . so when all of them join with david mamet and brian depalma and the result can be nothing short of explosive . kevin costner play a naive cop put on a mission to arrest al capone ( deniro ) . right from the beginning and this movie be a thrill ride . deniro be superb a capone and costner be good a elliot ness and and andy garcia be entertain a a sure shot young italian . but the real gem here be connery and in an oscar win performance . connery play an irish cop who join up with ness . he play the role very well and and deserve his oscar . also join the group be charles martin smith and a a accountant who show a deft knack for shoot at stuff . however and that not to say that the movie be without flaw . some scene be very unbelievable ( especially the one where connery meet his demise ) and some part ( especially at the beginning ) seem to go on too long . this and however and do not stop this movie from be fun . 8 . 5/10 .
