JM: There was one instance where we needed to consider the look of the visual effects and how far we could push that within the wider aim for realism, and that was in the night club sequence. Colt has been given some kind of psychedelic drug, and in a fight scene we experience the action from his drug-enhanced perspective. There’s a kind of animé theme, and early on we struggled with achieving the “magical” look, with the director requesting big colour shifts and dynamic sparkle effects. There was a fine line between creating something which might be too “magical” to be consistent with the realism of the rest of the movie, but this sequence still needed to convey Colt’s state of mind and sense of confusion in the moment. Ultimately, we shifted the RGB channels, blended with time warps and made the slow motion visuals fluid and organic, less graphic, so there’s a realism to the punch impacts, within the wider sequence look. We added chromatic aberration to the sparkles, lens flares and the kind of optical effects which we often add in typical visual effects. It’s a magical world within a real world!
