"The (two-week) ban on the movie by the Tamil Nadu government is legally and morally unjustifiable," CPI(M) state secretary G Ramakrishnan said in a statement here, adding the Supreme Court had in the past observed that it was not right to ban a movie after Censor Board certification.
The film ran into trouble after various Muslim outfits opposed it saying their community had been shown in "negative" light.
The state government has banned the film's screening for two weeks from January 25.
