This is a poster for Tron, a 1982 science-fiction film directed by Steven Lisberger. The film is about a computer hacker and arcade owner who is 'kidnapped' inside the 3D world of a mainframe computer. His only chance to escape is to participate in gladiatorial-style games.
Tron was groundbreaking for its combination of live actors and computer-generated, neon visuals. It took CGI (computer-generated imagery) to the next level, creating whole CGI-rendered scenes.
The tagline on this poster is effectively simple and direct. Coupled with the bold, central, neon-haloed figure, it is an engaging and striking design that immediately attracts your attention and sets the tone and genre of the film.
Tron was aimed directly at video game fans and became something of a cult film with an eventual sequel, Tron: Legacy (directed by Joseph Kosinski) released in 2010.
