The long grass field in Jurassic World Rebirth (2025) was grown in Thailand specifically for the production. Production designer James Clyne says getting the 4 acre field of the long grass to grow was one of the hardest parts of the production

Here is a quote from Jurassic World Rebirth’s Production Designer James Clyne from the commentary track from the home video release:

“When you put together these movies you’re like, ‘ok, what is the hardest thing going to be? Well, it’s probably going to be the lab, or it’s the boat.’ And then in the end it’s stuff like growing grass in Thailand in a really hot, arid area. We found this location, which was beautiful. It had all this, you know, stuff cliffs around it — but there was no grass. It was just literally dirt. And I’m… like ‘yeah, we can grow grass here, sure. We’ll bring some stuff in and lo’ and behold, it was really hot for weeks, it was really dry for weeks, and the grass just kept dying. Dying, and dying. We had just weeks to get this to a certain height. I think, Gareth, you wanted it at four feet height or something like that. And um, it’s just one of these things that kept me up at night, ‘cause like, my god, we can’t grow grass in Thailand. And we brought in a horticulturalist from the UK, we set up a whole irrigation system, and regrew the grass a third time and, thank god, it just sprung up within, I think, five weeks. It went from maybe a foot tall to this, like, four and a half, and we did like four acres of it.”

According to First Assistant Director Jack Ravenscroft, the grass was very sharp and would cut the actor’s hands. Scarlet Johansson’s hands had bandages that were digitally removed in post production.

Here’s is another quote from Prouction Designer James Clyne from the “Trekking Through Thailand” special feature on from the home video release.

“Gareth wanted this like grassy field at a certain height and we said ‘ok, let’s get in there and figure that out’. And we had to bring in professional horticulturalists to understand what it would take to grow grass in the amount of time that we had.”

“Only about three weeks before the actual shoot, the grass was only at knee-high and everybody’s going, ‘so, is this grass going to grow? Is it going to be here at that height on the day?’ And we of course said, ‘yeah, it’s going to be there,’ not knowing if it was but it happened.”
