The mishap occurred at Puppalguda at around 8:45 pm when the blaze, which started from a makeshift shed erected by a local shooting unit, engulfed a nearby residential apartment, Cyberabad Police Commissioner Dwarka Tirumala Rao told PTI.
He, however, said it was not yet clear whether the victims were residents of the building or comprise any members of the crew.
The exact cause of the fire is being investigated, Rao said, adding that the blaze spread due to a pile of plastic lying near the shed.
A short circuit could be the cause behind the fire, which has now been brought under control.
Andhra Pradesh Home Minister Sabita Indra Reddy has visited the spot.
