One of the most happening actors in Kollywood is Siva Karthikeyan and recently he shared his thoughts. He was speaking about the film 3 and was all praises for his co-stars Dhanush and Shruti Haasan. He recalled that though both of them were big names in the industry they made him feel very comfortable on the sets. He quipped that Shruti used to refer her as an innocent boy. Recently, Siva Karthikeyan came with the film Marina which got a decent response.
