Actor-director R. Madhavan, who is gearing up for the release of his forthcoming film Rocketry - The Nambi Effect, feels that not knowing about great scientist Nambi Narayanan is a crime.

Madhavan was interacting with the media at the teaser launch of the film, along with his co-director Anant Mahadevan and former Indian Space Research Organisation (ISRO) scientist S. Nambi Mahadevan, in Mumbai on Wednesday.
