Dookudu is not just getting thunderous collections but also is being applauded for its comedy and performances. Dookudu is all set to become the biggest grosser of this year in just one week. It is likely to surpass Pokiri and Robo collections in just three weeks, say trade pundits. However, there are doubts being expressed over the long run of the movie. NTR Jr Oosaravelli is coming on October 6 which will eventually slow down Dookudu.
