Our Power Star Pawan Kalyan is worried about his Re-make Gabbar Singh..

The immense success of the Salman Khan starrer Dabangg paved way for its remake it Tamil and Telugu. While in the Tamil version titled Osthe, it was Simbu who played the lead role, Pawan Kalyan was roped in to star in the Telugu version Gabbar Singh.

Osthe released a few months ago and this film did not meet the expectations that it had generated. This has upset Pawan Kalyan, say sources. The star has suggested to the director to make some changes to the script. Following this, several scenes including comedy has been included, say sources.
