Luma’s most significant contribution to the film is “French Connection,” sequence or the Train Fight scene. Carol Danvers fights atop a moving Los Angeles Metro train against a shape-shifting Skrull who has taken the form of an unassuming granny and who later shifts into a middle-aged man. All the while, Nick Fury and Agent Coulson race through the streets below to keep up with the train by car. While the train appears to speed by at a rapid pace with the characters fighting on top, it’s Luma’s visual effects magic working behind the scenes.
Luma's task was to keep the sequence linear and successive. While the setting looks like it takes place in in one location in L.A., the scene was actually shot in four different locations throughout the streets of L.A. It travels through West L.A., East L.A., and eventually moves towards Downtown. "Chris Townsend, the overall VFX Supervisor, mentioned that Marvel Studios wanted the sequence to be done by a studio which had an office in L.A., so that if we needed to, we'd be able to access the real world location for reference," said Luma VFX Supervisor Kevin Souls.
