Ram Gopal Verma's Darna Zaroori Hai is fetching mixed reviews both from viewers and critics. With its quintessential chills and thrills the film has managed to evoke fair amount of curiousity in people.

Just like Darna Mana Hai, Varma opts for multiple short stories instead of conventional single-narrative for DZH to make power packed punch. But what stand out is the ensamble cast he skillfully used for the horror flick.

It was Ramu's sheer passion for films which made Big B do DZH and that too for free.

"Now, what can one charge for just a day's work?" asks the ever humble superstar. "Ramu keep surprising people by doing unexpected things. So when he asked me to do one segment, I agreed. I don't think I've done anything similar to this in the past," he adds.

Also admits Big B," Actually, I'm petrified of horror films in real life. Ramu's Bhoot, where a ghost kept appearing. I can't tell you how tormented I was for months afterwards. Every time I went to bed I imagined that woman from Bhoot would appear from nowhere."
