LeBron James Nike Chalk commercial. The 30 and 60-second U.S. television spots draw its inspiration from LeBrons pre-game ritual of tossing talcum powder into the air at the scorers table before each home and away game. The pre-game ritual of LeBron has become a symbol of the ultimate Just Do It moment. The commercial also features cameo appearances by basketball players Greg Oden, LaMarcus Aldridge, Brandon Roy, Daniel Gibson, Anderson Varejao, J.J. Hicks and platinum recording hip-hop artist Lil Wayne.
