Put Yourself in the Movie is an HTML5 web app developed to promote the release of The LEGO® Movie for Warner Bros.

The app allowed fans to replace Emmet, the hero of the film with their own LEGO® avatar (generated with a separate web app) in the movie’s official trailer by entering a unique avatar code.

Users had the ability to preview their avatar in situ and add their name to the trailer’s title card before generating a personalised, shareable version of the trailer in which their character perfectly matched the actions and movements of Emmet.

The app was built with Marionette.js and leveraged Encodeo, Play Nicely’s bespoke on-demand video encoding service.

Built to be easily localisable by Warner Bros’ in-house team, it launched simultaneously across 7 different international markets. Over the course of the promotional campaign leading up to the film’s release, thousands of personalised trailers were generated and shared by fans all over the world.
