If you’re keeping track of these things, a Canada-based lawsuit claiming James Cameron‘s Avatar was based on someone else’s work has been thrown out. It’s the fourth legal victory since last year for Cameron, producer Lightstorm Entertainment and 20th Century Fox over similar allegations again the 2009 mega blockbuster. Fox said today a federal court in Vancouver issued an order dismissing the latest complaint filed by local writer and restaurateur Emil Malak, who alleged that the pic copied elements of his script Terra Incognita. Malak was seeking $100M but dismissed the claim after the first day of hearing on Cameron’s motion for summary judgment. Malak originally filed suit in 2010 in BC Supreme Court but dropped that case too.
