The Power of Visual Effects: When Wildfires Become Characters
In the world of cinema, visual effects (VFX) can transform a story, and in the case of 'Train Dreams' and 'The Lost Bus,' they bring devastating wildfires to life. These films, set against the backdrop of real-life tragedies, showcase the incredible talent of VFX supervisors, who create immersive experiences that leave audiences in awe.
Nearly a year after Los Angeles was ravaged by wildfires, two award-contending films emerged, each featuring deadly forest fires as a central theme. 'Train Dreams,' a Netflix original, tells the story of logger Robert Grainier, played by Joel Edgerton, who returns home to find his life and the forest he knew destroyed by flames. Meanwhile, 'The Lost Bus,' streaming on Apple TV, recounts the true story of the Camp Fire, a catastrophic wildfire in California's Butte County in 2018, through the eyes of school bus driver Kevin McKay, portrayed by Matthew McConaughey.
Both films presented unique challenges for their VFX teams. For 'Train Dreams,' the production chose to film in a forest already ravaged by fire, setting the tone for the film's emotional impact. VFX supervisor Ilia Mokhtareizadeh, known for his work on 'After Yang,' faced logistical challenges but was determined to create a solid foundation for the effects. He designed a massive lighting rig and smoke machines to capture the atmosphere, ensuring the film's visual integrity.
Mokhtareizadeh's team also lit small, practical fires to provide visual references for the CG-heavy wildfire sequences. However, for the iconic wall of fire in the distance, practicality was out of the question. "It had to be this kind of ominous monster in the distance," he explains, highlighting the challenge of creating a sense of scale and distance.
'The Lost Bus' VFX supervisor, Charlie Noble, faced similar challenges. His team chose New Mexico as the filming location due to its dry, hot, and dusty conditions, which could easily mimic the potential for a wildfire. They filmed in Ruidoso, a mountain village, and then moved to a backlot in Santa Fe, where they buried propane pipes to create controlled flames.
Noble's team utilized CGI trees and smoke to enhance the early fire sequences, and as the wildfire progressed, they replaced propane flames with burning CG vegetation to create smoke and embers. Metal trees and bushes with propane gas were also built to ensure safe and repeated burning. Additionally, lights were buried in the ground to add to the flame effect, creating a truly immersive environment.
One of the biggest challenges for Noble was managing smoke, especially during scenes with children on the bus. "Safety is paramount," he emphasizes, explaining the use of water-based smoke and the strict time limits for exposure.
Director Paul Greengrass made a deliberate choice to 'cast nature as the prime antagonist' in 'The Lost Bus.' This is evident in the scenes where the camera pans through the fire, showcasing the wildfire's relentless pursuit. This effect, achieved through a virtual 'ember cam,' adds to the film's intensity and the sense of being hunted.
In both films, the wildfires are not mere background elements but become characters in their own right. Mokhtareizadeh notes, "It really took center stage." John Messina, a retired Cal Fire assistant region chief who consulted on 'The Lost Bus,' praises the film's accuracy, saying, "It's one of the rare portrayals that precisely reflect what first responders and residents experienced that day."
