However Jiiva’s “Yaan” is garnering public attention without such strategies, by mostly word of mouth from Bollywood biggies. Bollywood mega star Amitabh Bachchan has now come out to the social media by expressing his appreciation for the director Ravi K Chandran. The cinematographer turned director earlier worked with the Big B for “Black.” Amitabh who is keen on social media has said that the trailer of the movie has come out quite impressive and a good thriller in the making, well there is no better publicity than this!
