The makers of Nani's Gang Leader had to postpone the film's release to September 13th after Saaho occupied its release date, August 30th.
However, Prabhas is set to return the favor to Nani. Apparently, he will be gracing the pre-release event of Nani's Gang Leader which will be held next month. An official announcement will be made soon.
Prabhas's presence will definitely add more buzz to Gang leader, given his nation-wide popularity.
