"Best Seller" is essentially a two character movie. On one hand there is Brian Dennehy as a veteran cop who also writes crime novels based on real events. On the other hand there is James Woods as a professional killer who has been spurned by his former employer (Paul Shenar). He seeks out Dennehy to try to convince him to write his story of how a now rich and powerful magnate rose to the top over the bodies of others.
The first part of the movie involves Woods trying to convince Dennehy that his story is on the level. The second part of the story covers Shenar's attempts to intimidate Woods and Dennehy and prevent the publication of Dennehy's book.
Woods and Dennehy play off of each other marvelously. Woods is cold and calculating as the hit man and Dennehy is torn between his sworn duty as a cop and his desire to get to the truth.
"Best Seller" is not for the faint of heart. There are scenes of graphic violence, which I feel are necessary within the context of the story. The film is worth a look if for nothing else than to watch two veteran performers at their best.
