Filmmaker SS Rajamouli said the only time he had sleepless nights while making 'RRR' was when he was shooting the animal sequence with actor Jr NTR. "That's...because we had a night shoot," added Rajamouli. Rajamouli earlier stated that they shot the animal sequence for more than 40 nights. "[It] involved almost 2,000 extras and was a logistical nightmare," he'd added.
