EXCLUSIVE: Film is about French artist JR’s huge participatory art project of the same name.

London-based WestEnd Films has taken international rights to Inside Out: The People’s Art Project, a feature documentary about participants in French artist JR’s worldwide art project of the same name.

Alastair Siddons’ film follows some of the 150,000 (and counting) participants in the ongoing ‘worldwide art adventure.’ Ordinary citizens are encouraged to express what they stand for.

Producers are Emile Abinal and WestEnd’s Sharon Harel-Cohen. Executive producers are Marco Berrebi, Leo Haidar, Sol Guy and Jane Rosenthal.

The film, a UK-France co-production, premiered at the 2013 Tribeca Film Festival. WestEnd Films starts sales in Toronto.

JR, whose full identity remains anonymous, won the TED Prize in 2011. He was granted initial funding to start the world’s largest participatory art project, inspired by his large-format street ‘pastings.’

The film tracks the evolution of the project as JR travels the globe to meet communities from Tunisia to Haiti to North Dakota and beyond.

“Alastair’s and JR’s film is a tribute to the countless individuals who continue to make the Inside Out project such a success in their communities throughout the world,” said producer Emile Abinal. “It is the most collaborative film project imaginable and we could not be more proud of it and what it represents: the transformative power of art.”

JR recently attracted attention by covering the whole of Times Square in New York. He has previously covered London’s Tate Modern. JR and his team will bring the Inside Out truck to London from Oct 3-13.
