Megastar Amitabh Bachchan, who is extremely fluent in spoken and written Hindi, offered to help southern actor Rana Daggubati with the language during the shooting of "Department".

Initially, Big B was unaware of Rana's weakness in the language. But later when he got to know about it, he decided to pull the young actor's leg.

According to a source, the 69-year-old veteran asked Rana to narrate tough Hindi words and lines.

Out of sheer respect, Rana made honest attempts to narrate the lines, but often failed. That only ended up giving him a chance to be tutored by the megastar himself.
