'Brahmstra' co-stars Amitabh Bachchan and Ranbir Kapoor seem to be having fun while at work as they went out for a walk in the city and clicked selfies.

The stars are currently in New York to shoot for 'Brahmastra', first from the trilogy to be produced by none other than Karan Johar.

Amitabh Bachchan wore a white sweatshirt with black track pants, while Ranbir donned a blue-green jacket with blue denim. The actors wore similar looking white sneakers and finished the look with trendy sunglasses.

This is the first time that Bachchan and Kapoor will be sharing the screen space.

Taking to his Twitter, senior Bachchan posted pictures of Ranbir and himself, walking in the city while clicking selfies.

"Out on a walk on the streets of NYC with THE Ranbir Kapoor .. selfies and all," read the caption.
