Measuring the Fear Factor
We placed a question near the very end of the video in Lumiere to ask each viewer to submit a slider rating indicating how scary they thought the movie would be based on what they saw in the trailer. After answering, Lumiere's conversations feature prompted each viewer for more information on why they submitted that 'scare' rating. Viewers rated the movie a 8.4/10 on the scare scale, mentioning the jump scares, atmosphere, gore, and suspense as top elements that influenced their response. Thanks to Lumiere's conversation feature, we not only captured the quantitative scare score, but also the qualitative information to understand what led to that score.

Predicting Box Office Interest

Using Lumiere’s custom variable tagging, we segmented viewer responses by their familiarity with the original film—without ever needing to ask additional questions mid-viewing. As expected, fans of 28 Days Later showed a higher intent to see the sequel. But the surprise? 90% of non-viewers of the original still said they were likely to see 28 Years Later in theaters. With Lumiere, we uncovered a broader-than-expected audience pool—valuable insight for distribution, media targeting, and marketing strategy.
