'The King Of Marvin Gardens' is a dark drama about two brothers who team up for an odd real estate scheme involving a Hawaiian island. Jason (Bruce Dern) summons his younger sibling, David (Jack Nicholson), a Philadelphia radio personality, to join him in Atlantic City to get the deal going. But when David arrives, he finds that a local crime boss has had Jason thrown in jail. David intervenes on his brother's behalf and succeeds in bailing Jason out. But the charges won't be dropped unless Jason forgets the Hawaiian venture. Two of the most watchable actors of the period excel in this unusual tale.
