The Lair

In a 2022 interview with Icon Vs. Icon, Neil Marshall spoke about some of the challenges of doubling Budapest for Afghanistan and bringing the script to life: "Trying to recreate Afghanistan and Russian bunkers in Budapest was certainly challenging. There is a sequence involving an elevator shaft. We knew we couldn't film it in a real elevator shaft, so we had to figure out how to shoot something like that. There are always those types of creative challenges. Also, finding US Army vehicles in the middle of Budapest isn't the easiest thing to do! We managed to find a Humvee from Romania, which belonged to a private collector, and drove it to the locations. You write things like these into scripts so easily without thinking about how you're going to pull them off. It's only when you get into production that you start to think, 'Oh, what was I thinking when I wrote that.' We only have ourselves to blame at the end of the day!"
