Producer Lagadapati Sridhar is upbeat that the Trailer of 'Naa Peru Surya' has become a big hit.  "I should say that the build-up for 'NPS' is as big as that of 'Avengers' in Hollywood.  Our film will be called a greater one than even 'Avengers'.  It will forever be etched in the hearts of the audience," the proud producer says.

"Bunny put in a tremendous effort for one year in terms of getting the body language, voice modulation, etc right.  It's unimaginable," he says about his hero Allu Arjun.

The film's pre-release event will be held tomorrow (Sunday, 29 April) in Hyderabad's Gacchibowli Stadium.  "It will be a special event as we have planned many LIVE entertainment items.  'NPS' has a song on which only Hollywood technicians worked.  Its promo will be featured during tomorrow's event," Sridhar reveals.
