Directed by M. Rajesh, the romantic comedy highlights a wedding sequence featuring Bhumika Chawla and Natty, while Priyanka Mohan's performance stands out. Sung by Madhushree with lyrics by Parvathy Meera, the Harris Jayaraj-composed track adds to the film's appeal. 'Brother' explores brother-sister sentiment and is expected to resonate with all audiences. This Diwali, it will compete at the box office with Sivakarthikeyan's 'Amaran' and Kavin's 'Bloody Beggar,' making for an intense showdown in Tamil cinema.
