I love movies about process, and this film is chock full of scenes showing how things get done.

The work may disappear - the documentary ends with an intentionally short-lived exhibition tied to an abandoned high-rise set for demolition - but the people, JR wants us to know, will always be there.

JR has pasted giant faces on everything from the favelas of Rio de Janeiro to the bridges in the centre of Paris. Paper & Glue, directed by its subject, follows him through the years as he tries to unite disenfranchised communities through art.
