Sunil has been going through a dull phase in his career. Most of his movies in the recent past haven't brought him much fortune. In this do or die situation, Sunil paired up with acclaimed director Kranthi Madhav for 'Ungarala Rambabu.' And it looks like this time Sunil with the help of Kranthi Madhav, is all geared up to impress the audience. Though the trailer starts off with the usual Sunil's comedy, it turns out to be that the movie has much more serious subject to offer. Prakash Raj plays a pivotal role in this flick which is all slated for a release on September 15. Check out the trailer here.
