"I met Shanu Sharma, the casting director. She found me and asked me to give audition. I came and qualified and that's how I became 'Virus Diwan', " Arjun said at the launch of Y-Films Thursday.
Arjun says it was none other than Salman Khan who discovered his acting potential.
"Salman Khan once took me aside and asked if I want to be a hero. I was 140 kilos then. I don't know how he found a hero in me. I started training with him. I was literally with him all time. And he cut me to 85 kilos, " said Arjun.
To be directed by Bumpy, "Virus Diwan" is a tech-based caper where Arjun plays the title role of a computer hacker.
Before facing the camera, Arjun worked as an assistant director.
"I wanted to be in the film industry, so I decided to be an assistant director. I worked in 'Kal Ho Naa Ho' and "Saalam-e-Ishq". I worked in two films of my father 'Wanted' and 'No Entry', " said Arjun.
The exclusive first looks of two new films were also showcased at the event.
"Luv ka The End", again directed by Bumpy that features Shraddha Kapoor and introduces Taaha Shah. It has a foot-thumping soundtrack by Ram Sampath and is slated for a May 6 release.
Another is a romantic-comedy against the backdrop of social networking and is interestingly titled "Mujhse Fraaandship Karoge". Directed by Nupur Asthana, it introduces four new faces - Saqib Saleem, Saba Azad, Nishant Dahiya and Tara D'souza. It also marks the Bollywood debut of desi folk-rocker Raghu Dixit as composer.
