Bala is up and running with his not-so-serious comic caper Avan Ivan starring Arya and Vishal in the lead. While he seems to have finalized the rest of the cast, the coveted heroine position was up for grabs until now.According to sources, Bala has zeroed down on Nivedita, an actress whose previous credits include Kadhai and Porkkalam. Although both the movies bombed at the BO, let’s hope Bala’s faith in Nivedita does not fall short.It is worth a mention here that Bala had already signed up Janani Iyer as one of the two heroines.
