Brahmastra logo launched at Kumbh on Maha Shivaratri 

Around 150 drones lit up the sky forming the Brahmastra logo at Kumbh on Maha Shivratri on Monday as actors Alia Bhatt, Ranbir Kapoor and director Ayan Mukerji came together for a one-of-a-kind film marketing initiative.

"It's the Brahmastra logo day... Our journey has just about begun and we are at the Kumbh mela, and we are very excited. Look up at the sky," Alia said ahead of the logo launch.

Ranbir said, "(I am) Very excited... can't match her energy, but super excited."

Ayan shared Alia and Ranbir's photograph on Instagram and captioned it 'Shiva and Isha', the actors' on-screen characters from the film.

Brahmastra, a fantasy adventure trilogy, which was originally scheduled to hit the screens on August 15, will now be released this Christmas. This is Ayan's third film after Wake Up Sid (2009) and Yeh Jawaani Hai Deewani (2013), both of which featured Ranbir in the lead. 

Brahmastra, bankrolled by Fox Star Studios, also stars Amitabh Bachchan and Nagarjuna.
