Actor Uday Chopra has a unique nickname for his elder brother, Aditya. He calls the successful producer "Voldemort", inspired by the main antagonist of the "Harry Potter" series.

"I'm off to a quiet dinner with Voldemort...that's what I call my brother (The one who shall not be named), " Uday posted on online networking website Twitter.

Uday and Aditya are sons of veteran filmmaker Yash Chopra, owner of Yash Raj Films (YRF).

While Aditya produces films, Uday has lately been spending time in the US and taking care of YRF Entertainment as its CEO. The new wing by the YRF banner is aimed at developing and producing feature films for the US and international markets.

In his acting career, which began with "Mohabbatein", Uday did films like "Mere Yaar Ki Shaadi Hai", "Dhoom" and "Mujhe Dosti Karoge".
