Actor Rana Daggubati says he had to turn down designer Vikram Phadnis' directorial debut "Nia", as he was completely involved in the shoot of SS Rajamouli's upcoming magnum opus "Baahubali".

The 30-year-old "Baby" actor said the bulky physique that he has acquired for "Baahubali" was not fit for the character he was supposed to play in Phadnis' film, which is a sensitive, slice-of-story and stars his good friend Bipasha Basu.
