Actor Vivek Oberoi, who will be seen as a supervillain called Kaal in the upcoming superhero film 'Krrish 3', says bad charcters have always attracted him and he is excited to play Kaal in the film. He says the character has an aristocratic aura and is a prince of darkness.

"Bad characters have always attracted every actor and it is so enjoyable to play a negative shade or character," Vivek, who earlier played negative in films like "Shootout at Lokhandwala", said in an interview.

"Like I am playing 'Kaal', I am very excited because there is an aristocratic aura around this character. This character is the prince of darkness. He is a super villain who is the king of his own world," he added.

Recently, Vivek's supervillain look in the film was unveiled and he is happy with the response he is getting for that and revealed he worked hard for more than three months on his character in the film.

"I did homework on the character of 'Kaal' for almost three-and-a half months, like what will be its look ? What kind of costumes will it have ? How will he behave ?," said the 37-year-old.

"The whole team worked on it. So it feels very nice when you get such reactions," he added.

Slated to release Nov 4, "Krrish 3" features Hrithik Roshan in triple role, while Priyanka Chopra and Kangna Ranaut will also be seen in key roles.
