Director James Cameron is to be sued by an Australian couple over allegedly stealing their idea and using it to create 1991 blockbuster Terminator 2: JUDGMENT DAY.

FILIA and CONSTANTINOS KOURTIS insist they created the character of a shape-shifting creature for their own film THE MINOTAUR in 1987, and that film-maker Cameron promptly pinched the idea for the Terminator sequel after seeing their production.

The pair's attempt to file suit against Cameron was initially snubbed by a Los Angeles district court as their screenwriter WILLIAM GREEN had previously lost the same case.

However, a three-judge federal appeals court has ruled that the movie-making Antipodeans are "free to pursue their copyright infringement claim... because they were neither parties to the Green case nor in privity with a party".
