Kamal Haasan, who is bankrolling the film under the banner Raaj Kamal Films International, shared the teaser of "Amaran" on his Twitter handle. Along with the teaser, he wrote, "Happy birthday dear brother @Siva_Kartikeyan. I wish you a long life. #Amaran. Delighted to release the title teaser of the movie."

Sai Pallavi also took to social media to share a heartfelt note about the film and extend birthday wishes to her co-star. She wrote, "Happy Birthday dear @Siva_Kartikeyan! I'm so happy that the world gets to see you embody #MajorMukundVaradarajan & shower you with all the love & respect they have for him! As artists, we know how much we long for such career-changing films! I’m happier that it’s happening when we’re working together in @Rajkumar_KP sir’s film! Here’s #Amaran for you and your dear fans."

"Amaran" features Sivakarthikeyan in the role of an Indian Army Rashtriya Rifles officer. The action drama is filled with intense emotional moments and a patriotic theme, as the officers fight for Kashmir.

The music of "Amaran" is composed by GV Prakash, cinematography is handled by CH Sai, and editing is done by R Kalaivanan. Directed and scripted by Rajkumar Periyasamy, known for the 2017 film "Rangoon," "Amaran" promises to be a gripping blend of action and drama.

Sivakarthikeyan created a niche for himself in Tollywood with films like Varun Doctor and Don and Sai Pallavi has an immense craze among movie lovers. Expectations are high on the project as Sai Pallavi is not seen on screen for a longtime. Movie lovers are waiting eagerly to watch the film on the big screen.
