The comments came a day after Union Minister Pon Radhakrishnan demanded removal of dialogues portraying what he termed as "untruths" about the Goods and Services Tax (GST) in the Vijay-starrer movie.
"Mr Modi, Cinema is a deep expression of Tamil culture and language. Don't try to demon-etise Tamil pride by interfering in Mersal," Gandhi said in a tweet.
