After the success of Nannaku Prematho, Jr NTR is set to start shooting for Janatha Garage from February 22 at Saradhi studios. “A big garage set has been designed by art director A.S. Prakash and the director is happy with it. The set looks completely original and they are buying 15 to 20 old cars to keep in it," adds the source. The makers have spent nearly Rs 3 crore on the garage set. Apart from Jr NTR, director Koratala Siva is also looking to continue his phenomenal run after the superhit Srimanthudu.
