He says technology and equipment alone aren't enough to make a technologically high-end film.

"We have the latest technology and the equipment, but we lack trained technicians. For 'Ra.One', we had hired 50 foreign-trained technicians. I would love to work in 'Ra.One 2', but it's not easy. For a film with a different genre like 'Ra.One', I'll need at least two to three years for preparation," Shah Rukh said.
