Madhavan, who is currently shooting his directorial debut, Rocketry - The Nambi Effect -- a biopic on ISRO scientist, Nambi Narayanan -- has wrapped up the film's first schedule in Russia. The actor, who also plays the titular role, has interestingly completed the shoot five days prior to the schedule, despite shooting in unfavourable weather conditions.

The actor took to Twitter to make the announcement.

Produced by Tricolour Films in association with Vijay Moolan Talkies and Saffron Ganesha Entertainment, the film also stars Simran and Rajeev Ravindranathan. Rocketry will be getting a release in three languages -- Tamil, English and Hindi -- by the end of this year. 

Nambi Narayanan is a former senior ISRO official, who was wrongly accused of espionage and arrested in 1994 for allegedly selling India’s trade secrets to Pakistan. The CBI dropped charges against him in 1996, and the Supreme Court declared him not guilty in 1998.
