Resonating with environmental advocacy such as energy reduction, Spider-Man's infamous mantra "with great power comes great responsibility" was part of a marketing strategy endorsing the "green production" of the 2014 blockbuster The Amazing Spider-Man 2.

Undertaking a material analysis of filmmaking, the article firstly locates how "power" can be conceptualised within the film, its production context, and the surrounding Hollywood industry.

Questioning the production of environmental encounters throughout the marketing campaign, the article asks what worlds are produced in the process, and how.
