Pinto plays Josh Brolin's love interest

The unlikely pair were seen shooting together in London, with Woody Allen having to order artificial rain for a romantic sequence in the yet-untitled film, reported Daily Mail online.

Earlier this month the 25-year-old actress had made her first public appearance with Patel, who is six years her junior, together as a couple at Somerset House for an outdoor screening of 'Slumdog Millionaire'. The couple met while filming the hit rags-to-riches film in Mumbai, which won eight Oscars.

The 43-year-old Brolin who won an Oscar for his supporting role in the biopic 'Milk' this year, is married to Hollywood beauty Diane Lane for the past five years.

Pinto and Brolin are a part of the star studded project which includes names like Antonio Banderas, Anthony Hopkins, and Naomi Watts.
