Jann Mardenborough on Finding Secret Racing Lines in ‘Gran Turismo’

Were there other areas in the script where you had strong feelings about how the story needed to be told?

The other example would be GT Academy, and how that process went down. My favorite part of the movie is the first 40 minutes because it explains the process of where I was in life, my situation, living at home. I was 19, kind of with no real direction. And it explains how I found the academy, how I was good at the game, how I was working in a retail store. Neill [Blomkamp, director] was aligned on that as well because it really tees up the whole story, you have to know that beginning in order to understand the story.

In the movie, there is a major plot point based on your finding a faster way around the track from gaming, that the other drivers don’t use. Did you really find a new racing line from playing Gran Turismo?

In the movie, at Le Mans, there’s a certain line that I use in a particular corner that I found on the simulator. There’s a half-truth in that. I have found certain different racing lines. At one track in particular in Japan called Fuji Speedway, there is a corner called 100 R, which is Turn 4, Turn 5, quite a high-speed corner. I found this particular line doing it much tighter in Formula 3. On the sim—I was using Gran Turismo at the time—I found a tighter line was more consistent for me. And compared to some others, they were using a slightly wider line, exiting four and then going into five, whereas I would kind of stay quite tight.

It’s not Le Mans, but certainly, I found different lines in real life, at different circuits. I have stumbled across a different race line in the wet, at Fuji again, while doing Formula 3. At the exit of Turn 1, beyond the white line, there’s some “grasscrete,” we call it, like some cobbled stones almost. But they’re quite grippy. And I remember being out of control arriving at turn one in an F3 in a test session, very wet. Not going to make the apex. Definitely not going to make the apex. And I just cranked a little lock at the last minute and my front left tire hooked onto these cobbled stones that had quite a lot of grip on them.

And that was my line in the wet. It didn’t work in a bigger car because the cars were less nimble. It didn’t work in Super Formula, but it worked in an F3 car. And I’d always gain a 10th and a half compared to my teammates at Turn 1. I had the team manager telling me I kept missing the apex at Turn 1, but I was actually quickest. I mean, I didn’t find that line specifically in the game, but the line at Turn 4, Turn 5—that was through playing GT. So there’s a half-truth there. That’s the long answer.

Like many girls, she planned to be a vet-astronaut-artist, and came closest to that last one by attending UCLA art school. She painted images of cars, but did not own one. Elana reluctantly got a driver’s license at age 21 and discovered that she not only loved cars and wanted to drive them, but that other people loved cars and wanted to read about them, which meant somebody had to write about them.
