MUMBAI: Author Jonathan Lethem will deliver the ninth annual State of Cinema address at this year's San Francisco International Film Festival, said The San Francisco Film Society.

Lethem's talk will investigate the "ecstasies of influence" in cinema and discuss how cultural movements like Occupy Wall Street, new media like YouTube and grassroots arts movements have the capacity to affect film culture.

Speakers who have spoken earlier include Christine Vachon, film editor Walter Murch, Wired publisher Kevin Kelly, actress Tilda Swinton, writer/director Brad Bird and cultural commentator B. Ruby Rich.

"Jonathan Lethem is the perfect person to explore current social and cultural movements and their possible aesthetic, political and commercial influences," said Film Society director of programming Rachel Rosen.
