Thala 57 is all set to begin shooting next month, but the heroine for the film has not been finalized yet. Industry sources are saying that Kajal is the top contender for the role. Film’s director Siva has approached several leading heroines but many of them are busy with multiple projects and couldn’t allot bulk dates for Thala 57. Earlier Siva had approached Tamannaah, Nayanthara and Anushka for the role. The movie is produced by Sathya Jyothi Films and is expected to be shot mostly in foreign locations. Anirudh Ravichander is the music composer of Thala 57 and Vetri will be handling the camera.
