Roshan's upcoming 'Krrish 3' is the third film in the sci-fi genre after hit films 'Koi Mil Gaya'and 'Krrish'.
"Krrish has been established as a superhero. The difficulty was how to make a super villain. We had to make sure the powers of super villain were more than that of superhero. It is all been very difficult. To make a villain is very easy in Hindi films but to make a super villain is very difficult," Roshan told PTI.
Roshan contemplated putting 'Krrish 3' on back burner as creatively things weren't working out. "In a superhero film there is a superhero and a supervillain. Hollywood makes a one and a half hour film... They meet, they fight, they meet they fight. But the content value is not that much. In Indian films they need content. I wasn't getting good content which would satisfy me," he said.
"This is a new genre for me because we don't make such kind of films. We are not trained to make such films. Hence, it was challenging as well as exciting. Hollywood has been making such films for last 40-50 years," he said.
"When you know your story is strong, then all special effects, vfx etc are just decorations. I see a lot of films and special effects are a part of your imagination," he said.
