The first combo movie of Superstar Mahesh Babu and director Koratala Siva has been creating lot of buzz in the media, ever since the latter's debut directorial venture Mirchi released in theatres. Finally, the director has put an end to all the speculations by launching the film. The makers had a grand opening ceremony in Padmalaya Studios this morning (August 11), but Prince was not present on the occasion. UTV Motion Pictures was supposed to produce the untitled movie of Koratala Siva and Mahesh Babu, but it did not happen due to some reasons. Now, Mythri Movies is producing it. Talking about the film, the director said, "It's an out-and-out commercial project that's sure going to appeal to Mahesh's fans. Devi Sri Prasad has been roped in to compose the music, while the rest of the film's cast is yet to be finalized." Soon after the launch of the movie, Koratala Siva took to his Twitter page and assured that he will work hard to make it the best film. He tweeted, "Thank u all for the wishes. Will put my best to make it the best." Meanwhile, he also cleared the air about its release stating that it will hit the screens in Summer 2015. He added, "No. Planning for a summer release." Mahesh Babu is currently shooting for director Srinu Vaitla's upcoming film Aagadu. Hence, he reportedly could not attend the launch of his movie with Siva. Once he wraps up Aagadu, he will take up the production of this new film. However, the muhratham was a grand affair and directors VV Vinayak, K Raghavendra Rao, Mahesh Babu's wife Namrata Shirodkar, producers Dil Raju, Anil Sunkara, Gopi Achanta, Bellamkonda Suresh, Sai Korrapati and many politicians attended the opening ceremony.
