We teamed up with 8th Wall to create an elaborate combination of an image tracker and augmented world effect that was available as a WebAR experience. As the premiere was a private event, the theatre inside BFI Southbank and the avenue outside the building were cordoned to ensure that premiere guests only could access the experience.

In the cordoned-off areas, guests found lollipops stands with QR codes which they could scan with their phone cameras as they were waiting to be admitted into the theatre. After scanning a QR code, their mobile web browsers prompted them to point their cameras at a Vigil promotional banner outside the BFI Southbank building.

Once their phone cameras had tracked an image of the promotional banner, the augmented world effect was activated. In front of the user emerged a large 3D model of the HMS Vigil submarine from a projection of water on the ground, giving users a sense of how the submarine would have behaved if it truly was out at sea.

Sounds of alarms, sirens and crashing waves can be heard throughout to emphasise the realism within the AR experience, and guests also had the opportunity to walk around the submarine to grasp its magnitude. The experience ended with the submarine submerging into the sea projection, before guests were directed to watch the official trailer for Vigil on YouTube.
