"The Grand Championship of Poker", held at the Golden Nugget Hotel in Las Vegas, furnishes the backdrop for this cleverly constructed mockumentary that will please aficionados of the card game, although viewers not conversant with the rules of poker will understandably be more interested in the personalities involved, thanks to the able leadership of director Zak Penn, who provides his cast with only a briefly outlined scenario from which to work. This, then, is primarily an improvisational work, with the actors representing actual well-known poker tournament contestants, all the while not themselves knowing the film's outcome, since they are engaged in ongoing competition with highly proficient professionals, contending for a winner-take-all prize of $10 million. Resourceful editing is the determinant to success for an episodic affair of this sort, and that duty is capably handled by Abby Schwarzwalder, being of particular value during the production's earlier segments, when a wide range of defined character types is created by director Penn. The film loses much of its impact during its lattermost sequences as a result of poker jargon being extensively utilized, and probably not comprehensible to a good many viewers. The Anchor Bay DVD release enjoys outstanding audio and visual quality and offers a liberal number of interesting extra features. These include: a brace of alternate endings; some truly comedic deleted scenes that have optional commentary by Penn, writer/executive producer Matt Bierman, and actor Michael Karnow; "Wild Cards" - a goodly amount of footage that profiles major players along with some cameo roles; a full-length audio commentary with Penn, Bierman and Karnow, marked by the director's efforts to keep the other two focused upon the film; and a large group of selected scene commentaries with Penn and Woody Harrelson, in addition to one with the director and players Cheryl Hines and Ray Romano. From among a large collection of talented performers we may enjoy some excellent turns, acting honours going to Chris Parnell as a social misfit who is also a genius at poker. These extras, taken together, will comprise the principal reason for a majority of those who are not fans of poker playing to acquire this work, their entertainment value offsetting any constraints caused by a self-destructing effect fashioned from the game's usage of poker nomenclature, a failing that will leave many viewers adrift.
