TIFF: Director Luc Besson bio of Burma's Aung San Suu Kyi

Luc Besson is known for producing action thrillers like Nikita, The Professional and The Fifth Element, and he also penned the children's fantasy series that began with Arthur and the Minimoys, but he explores new territory in The Lady, his portrait of Burmese pro-democracy activist Aung San Suu Kyi.

With Burmese friends giving him a thumbs-up for the new drama, Besson noted that he's "never felt so proud" of a film.

The French director, screenwriter and producer sat down with CBC/Radio-Canada during the Toronto International Film Festival — where The Lady is being showcased as a gala — to discuss actress Michelle Yeoh's portrayal of Suu Kyi and how he'd like to see the movie become the most popular "undercover film" in Burma, also known as Myanmar.
