Rajshri Productions favourite character Prem, essayed by actor Salman Khan earlier will now get a younger sibling Arjun Kapoor. Kapoor will play Salmans brother in their upcoming film Bade Bhaiya and sources revealed that, Sooraj Barjatya has finished the script. He wrote it keeping Salman in mind. They now need a young actor to play the parallel lead in the film. After watching Ishaqzaade, Soorajji was impressed with Arjun's performance. He arranged a meeting with Arjun and offered him the role. The story is about two brothers. The younger one is a rebel. The film will show how the elder brother mentors him and turns him into a well-behaved man, revealed the source. In real life too Khan has mentored Arjun to join the industry as an actor rather than a director. Arjun said, Salman is my elder brother. He had told me that I was cut out for acting. But I was really obese (140 kg), and couldn't imagine myself as an actor. Salman literally took me under his wings... He believed in me and that's why I am here today.
