Mega star Nagarjuna moved wife Amala beyond tears, with his overwhelming performance in devotional film 'Om Namo Venkatesaya'. Naga revealed that she was so touched by the movie, especially its climax, that she remained speechless and held his hands for a long time. Not only her, even Chiru was in tears as he watched the movie. Nagarjuna has given his best so far, playing the role of legendary saint Hathiram Baba, who brought the sacred streamlines to Tirumala temple. Touted to be a musical, 'ONV' has received brilliant response in Telangana and Andhra Pradesh.
