The theme of the movie is based on audio and video.... It means how video and audio are part of each other and one is incomplete without the other. One is dumb but his acting is bold and other is old with a voice of a gold. The concept was awesome as i said but the film's story is kinda messed up. It starts.....continues but in middle it somewhat sways to and fro....kinda stretches the story. I was waiting for such movies with concepts coz such movies are not there in our cinemas anymore. It was due to this that i watched this movie(and for Amitabh bachchan too). As you see.......in Hollywood, they have great conceptual movies like one being made on Stephen Hawkins.... I see that such kind of movies have been started being made in Indian cinemas too which have good concept... All they need is a bit improvement. Still actors have done a great job as it is first time any movie has made me to review it.
