Answer
Adam Curtis used collage to explore sociology, psychology, etc. in Pandora's Box (1992). He has continued to use this method in his later works, such as The Century of the Self (2002), The Power of Nightmares (2004), and Bitter Lake (2015). Curtis's collages are often made up of clips from old films, television shows, and news reports, which he juxtaposes in order to create new meanings and interpretations.
