The celebs will begin facing off against each other in matches of the Scrabble-like word-building game from publisher Zynga Inc. on Sept. 27.

Norton will be playing for the Maasai Wilderness Conservation Fund. "The Bourne Legacy" and "Moonrise Kingdom" actor says he is confident that he will dominate the tournament. 

Other celebrity players for the $500,000 in prize money include Eva Longoria, Kristen Bell, John Legend and Boston Celtics captain Paul "The Truth" Pierce. Norton says his stiffest competition might come from Snoop Dogg because of the rapper's experience with wordplay.
