Avatar 2 story resemblance from Dhanush movie
A son is killed in an enemy attack at Narappa. The hero battles the villains to save the rest of the family at the story's climax. The script for avatar 2 is likewise remarkably similar. narappa is an official remake of Dhanush's asuran and we are sure the movie has an uncanny resemblance. After the first installment's release in 2009, the story for avatar 2 was written.
Therefore, it is unlikely that james cameron was inspired by the 2019 film version of Vetrimaaran's novel. It's amusing if someone claims to have seen Naarappa or asuran before altering avatar 2's original plot. But the degree to which the two movies resemble one another is quite astounding. Unquestionably a case of a highly peculiar coincidence.
