Mangaatha was started with out much-hype in August 2010 without finalizing the other lead cast. Initial reports claimed that the makers of the film signed Neetu Chandra to play the love interest of Ajith Kumar in the film but later it was revealed that Trisha Krishnan was pairing up in the movie. Telugu actor Nagarjuna was roped in to play the second fiddle but he opted out later citing date issues. Then, Arjun Sarja replaced him and other cast was finalized.
Ajith Kumar starrer Mangaatha is not all about betting during cricket matches but it explores all forms of gambling. As the actor himself claimed before, there are five characters in the film, all bad men and he is the worst among them. Rest other gang members of the actor are played by Vaibhav, Premji Amaren, Mahat Raghavendra and Ashwin Kakumanu. While, Trisha Krishnan plays the female lead character, Arjun Sarja plays the role of a CBI officer. It is said that the director took inspiration by Steven Soderbergh's crime thriller 'Ocean Eleven' but the makers of the film have denied the reports.
The single track of Mangaatha titled 'vilaiyaadu mangaatha...' was released on 20 May 2011, to create buzz through this new marketing strategy. As expected, it was well received by the audience. However, the release of the complete album, which was postponed for several times, hit the stands on August 10. The Sony Music product has eight tracks and those songs have added fuel to the expectations of Thala's fans.
Venkat Prabhu directorial Mangaatha is produced by Dhayanidhi Alagiri. It has Sakthi Saravanan's cinematography and Praveen KL-NB Srikanth's editing. The distribution rights of the film went through several hands before landing in the safe hands of Radhika Sarath Kumar's Radaan Media Works. Sun Pictures has acquired the satellite rights of the Tamil movie, which is hitting the screens on August 31.
The moderate success of his last two movies made Ajith Kumar to be cautious about his 50th film. The actor, who had seen the fate of Vijay's 50th film Sura, went on to hear many stories and among those subjects, he showed interest towards Gautham Menon's proposed project, which was titled Thuppariyum Anand. Later, all of a sudden, the actor shelved the movie for the reasons best known to him and signed Venkat Prabhu's project Mangaatha.
