A film launch that played back the audience's own expressions.

Film launches live or die on attention in the first days of release. A large-format billboard delivers scale, but scale alone does not make anyone stop.

Quividi's expression detection let the screen respond to the people in front of it, mirroring their expressions back as emoji characters. The interaction itself became the advertisement, and engagement was measured as it happened.

Passers-by stopped, participated and photographed the result, turning a media placement into an event that travelled beyond the site itself.

The most effective creative in public space invites the audience into it.
