NTR tried something different with Nannaku prematho and 'Janatha garage' recently apart from his regular concept. His looks are very new in these movies and entertained audience.
NTR doesn't show interest because both the movies are experimental. Sources say that NTR is planning to act in a Mass masala entertainer. So, two of the directors are busy in writing the script for him. Let's wait and see what movie will he do for his next.
