Mumbai, Oct 26 (IANS): Technological advancement has lent speed to the film shooting process, says veteran actor Amitabh Bachchan, who feels the filming schedule of his upcoming political thriller "Sarkar 3" might wrap up before the scheduled time.

The 74-year-old wrote on his blog on Tuesday night: "The usage of multiple cameras prevents the time taken in shifting and relighting another shot for the close-up or the long shot, because the multiple camera set up gives the director a facility to use different lenses at different angles, so that the set up or the machine does not have to move about, or the actor to keep re-preparing himself or herself for the next shot.

"The digital camera, now in use, is a chip of endless time and storage. So we carry on without stopping to run the camera. It is just such a convenience of so many sorts and most importantly of speed."

"And so what happens... We finish the schedule ahead of time. Which is what it looks like is going to happen with 'Sarkar 3'. Finish perhaps many days ahead of schedule," he added.

"Sarkar 3", written-directed-produced by Ram Gopal Varma, is set in the world of politics and crime. This is the third instalment of the "Sarkar" film series. It features Amitabh alongside actors Manoj Bajpayee, Jackie Shroff, Yami Gautam and Ronit Roy.
