Story and Screen play : The story is pretty much similar in both versions. The first half is inch by inch remake from English version. However, I didn’t liked the second half in both versions. In English, it suited for western audience and there fore English was a better one. In Tamil, the inclusion of needless comedies like chasing each other in hotel was rather annoying. If Anushka is not getting married to Vikram, why should there be a un necessary romantic song ? not convincing in Tamil.
Casting : Full credit to vijay. The casting is just perfect for every single character. Vikram as usual did a walk in the park. Special mention should go to the baby Sara and Anushka who made an impact. Though came for short time, the 4 friends was really a delight to watch. Santhanam, black pandi, m s baskar did the home work well for the story. Highlight in tamil version is the addition of mynaa fame Amala paul she very well added the sweet flavor part
Music : Again full marks to GV Prakash. The beauty of Inidan cinema are the songs. In this movie, the songs gelled so well with the story. The story telling song is excellent one, the initial papa song is feel good, the background song when vikram raises sara alone is heart warming. Above all, I really loved the 2 theme music moments were vikram and sara exchanges the actions. Eye jerking. This is the highlight difference from English and so touching moment. Music can speak a lot better in emotional scenes.
Vikram Vs Sean Penn : Sean got the Academy award for his performance in 2001. Personally, I liked vikram’s performance better than Sean but I can see he got lots of inspiration (synonym for copied) from Sean and in many scenes he just repeated it. However, one needs talent to do that too ;) What keeps vikram at top is he is the same one who did multiple personality disorder in Anniyan, visually impaired poor singer in Kaasi, rough and tough seeyan in Sethu, grave yard maintanace villager in Pithamagan etc., the history that Sean doesn't have.
Overall, a must watch film (Deiva Tirumagal) for the individual performances and music.
