A FEW GOOD MEN, with Tom Cruise, Demi Moore and Jack Nicholson. Directed by Rob Reiner. On Edko and Ocean circuit. THIS Castle Rock Entertainment production oozes class from its violent opening to the torrid courtroom finale. Director Rob Reiner (Misery, When Harry Met Sally, Stand By Me ) displays an uncommon degree of professionalism in his execution of this courtroom drama about discipline versus the rights and duties of the US Marine. A Few Good Men is based on the successful Broadway drama by Aaron Sorkin, and benefits from the original play's strong plot, script and adroit use of language. Add to this Reiner's acute sense of cinematography and humour and you have a film worthy of the many Oscar nominations it has received. It has an enormously bankable cast, but all praise for their efforts is well deserved. Cruise, despite what many people would like to think, isn't just a pretty face. He has become an accomplished actor over the years, and is perfect as the flippant Lieutenant J. G. Daniel Kaffee. Kaffee is an offhand, arrogant and glib lawyer, the ve ry antithesis of Lieutenant Commander Joanne Galloway (Demi Moore). The two are brought together over the case of two young Marines brought to trial over the murder of a member of their platoon during a disciplinary action. Kaffee, as usual, wants to plea-bargain, to avoid any real involvement; Galloway wants to take the case to court. She eventually prevails, and the young lawyer goes after justice with the establishment snapping at his heels. The very core of the establishment in this case is represented by Colonel Nathan R. Jessep, a part taken by Jack Nicholson, and a part in which he revels. The snake-eyed veteran actor does a magnificent job of portraying a man only just in control of his power. A Few Good Men isn't without its faults (it decays into pro-American gung ho-ness in the penultimate scene), but it is highly rated and should be seen at the earliest opportunity.
