Was Manam poster just to draw eyeballs?

Going by the first look poster of Manam, audiences are in for a surprise because it has successfully grabbed eyeballs and even made dialogue in the audiences. But, was this poster merely used to grab attention or is the film really based on how its being speculated.

It would be wonderful to see if as depicted in the posters, the Akkineni family members don the same roles. The reason i say wonderful is because its something novel and will be a new experience for audiences to enjoy provided it doesn’t turn out to be a joke on the filmmaker.

As per the poster, Naga Chaitanya is playing the role of the grandfather, Nagarjuna as son and veteran actor Nageswara Rao as grandson. We have wait to find out if all this was only promotional gimmick.
