Dashavatar (originally Dasavathaaram) is a 2008 sci-fi action epic directed by K.S. Ravikumar. Kamal Haasan wrote the story and achieved cinematic history by playing ten distinct roles, including a biotechnology scientist, a giant ex-CIA assassin, and former U.S. President George Bush. The story follows a frantic race to secure a deadly, stolen bioweapon. Kamal Haasan's ten unique characters—ranging from a Japanese martial artist to a 12th-century priest—intersect through chaos theory and the butterfly effect. The thrilling narrative ultimately culminates during the 2004 Indian Ocean tsunami.
