Blind, deaf: Stars for different roles!

Tollywood stars are slowly coming out from their comfort zone and are game for some experimentation in the characters they portray on screen. Though none of them have not yet signed drastically different roles but future seems bright in this regard. A big star like Ram Charan accepting a role that has hearing deficiency itself is a big step in this path.
And then two other stars are playing as blind persons in their next movies. Ram Charan is playing the role of a deaf (not exactly deaf, but who has some hearing problems) in director Sukumar's new movie that was recently launched. So far, Ram Charan either played mass action hero characters or classy cop roles. So, he is ready for some daring steps.
Ravi Teja will be seen as Hrithik Roshan appeared in his recent 'Kaabil'. Ravi Teja recently announced a movie titled 'Raja The Great' in the direction of Anil Ravipudi. In this movie, he is blind guy. The first logo poster itself depicted the 'dark world' he lives in.
Raj Tharun is already working in a movie titled 'Andhagadu' in which he is blind. In the movie title's Telugu logo, 'Andha' (blind) was stressed so that people can easily get it.
Let's see how many other stars would follow and do experiments.
