In keeping with the film's ambitious theme that traces the events leading to the India-Pakistan war of 1971, Romeo Akbar Walter has been shot across 14 cities in India, and Nepal. While the extensive shoot could bog down many, director Robbie Grewal says that the unit wrapped up the shoot of the John Abraham-starrer in less than 50 days.

"We had a total of 14 cities — spread over Gujarat, Mumbai, Kashmir and Nepal — to be covered in a 49-day schedule, and we wrapped it in 46 days. Honestly, we could do this because we had done extensive planning during the pre-production stage," says Grewal.
