Blunder: ANR Taller Than Late NTR?

Thespians late NTR and late Anr were considered to be two eyes of Tollywood those days. During 1950s and 1960s, both the heroes shared the number one position jointly. They became good friends and would maintain healthy professional rivalry between them which made both of them 'Mahanatulu'. 

It is a known news that Natasimham Nandamuri Balakrishna is essaying the role of his late father NTR in NTR film. Also, we are aware of the fact that hero Sumanth played the role of his grandpa, Anr.

Team NTR has recently released a pic of NTR and Anr in which the actors were seen smoking cigarette. Well, the poster impressed many and the expectations were obviously increased on the film again. 

However, everything is not so well with NTR. Cine critics found a huge blunder with Sumanth's Anr getup. With best of everyone's knowledge late NTR was taller than late Anr. In such scenario, how can 6.2 feet taller Sumanth is shown as Anr? He looked taller than Balakrisshna, who played NTR in the film. Hope, the director gets his mistake rectified with some VFX shots in correcting heights.
