Essencialmente, porque é isso que o diretor, Wayne Kramer queria.
De uma entrevista ...
It was very expensive to light and the producers were trying to talk me out of it — which I’m glad didn’t happen. I was doing some ice hockey research on the internet and came across this Jet Ice black light paint and immediately thought that would be amazing to capture on film.
I don’t think we quite executed it the way I had in mind — due to technical difficulties and lack of time — but I envisioned more bullet impacts in the ice with the ice shattering into different colors and exploding through the air. I think we got just a hint of that; we were more successful with the fluorescent pucks and the DayGlo jerseys.
I also wanted the scene to be a significant set piece — this is where it all goes down, so to speak, and I wanted the backdrop to be memorable.
