Hugh Jackman has more than a week to fulfil his promise to be vegan, as the nutrition guide where he says "there's every chance that I will be a vegan by the time you read" is about to hit the stores within a week.

Brendan Brazier's "Thrive: The Vegan Nutrition Guide to Optimal Performance in Sports and Life" is set to be on the market starting September 14.That's a week from now.

Can and will the Australian action star turn vegan a week from now? The New York Post quotes a representative for Hugh Jackman as saying the actor is still not vegetarian.

The actor credited the diet for the additional 20 pounds he put on for his role in the 2009 movie "Wolverine." Hugh Jackman wrote a foreword to Brazier's book noting that he is no longer interested in the "at any cost" part of the equation when he prepares for the role.

The actor will reprise his steel-clawed character in Wolverine 2 which is set in Japan and is penned by Christopher McQuarrie. The sequel begins with Hugh Jackman's character drinking at a bar in Japan where X-Men Origins: Wolverine ended.

Logan, Wolverine's alter ego, will have a forbidden romance with a Japanese woman who was promised to marry another man. This leads to a clash between Logan's claws and the woman's father and brother who are samurais.
