Suriya plays Athreya which is highly negative. When I narrated the script ; he was initially apprehensive whether audience could accept him in such a villainous portrayal. I told him that only he could do it & that is the novelty of the script. I also said that character will stand strong among all the characters. Actually 24hours work is not enough for Suriya. If a day has more than 24 hours he will only work. Pulling three different roles is not a easy proposition. Each required a different make up & look . But the method actor has given a power packed performance. While Samantha & Nithya Menen are paired opposite to Suriya . Saranya Ponvannan appears in a important role. It’s not a routine mother role . A particular color tone is maintained throughout the movie. We had a schedule in Poland. We could get the 90’s train ; bikes which is required for the script. Rahman sir has given new sound to album 24 says director Vikram K Kumar.
