Calling the Iranian director "a true artiste", Kashyap wrote alongside the post that he hopes Payami's answer "puts enough shame in our controversy mongers"
"Secret Ballot" filmmaker now has the movie and will see it soon, he added.
Earlier, Kashyap had sent the link of "Newton" to the producer of the Iranian movie, Marco Muller.
Muller, who saw the film, told Kashyap that "Newton" was "definitely no rip-off from our 'Secret Ballot (even if the general concept is the same)."
Kashyap shared Muller's response on social media. Muller, in his response, said, "...there is not even a hint of plagiarisation."
"Newton" revolves around a government employee's struggle to conduct election in a conflict-hit area of Chhattisgarh, while "Secret Ballot" focuses on a woman ballot officer, who visits a desolate place in Iran to convince people to cast their vote.
