In the highly-anticipated sequel to Doctor Strange from director Sam Raimi, Doctor Stephen Strange teams up with a mysterious teenage girl from his dreams who can travel across the multiverse. They battle multiple threats, including other-universe versions of himself, which threaten to wipe out millions across the multiverse. In this epic journey, they seek help from familiar faces such as Wanda the Scarlet Witch, Wong, and others. 

The film first features a thrilling Tentacle Creature Battle sequence, which was made possible by Luma Pictures, who worked closely with director Sam Raimi and VFX Supervisor Janek Sirrs to create this visually stunning battle. The scene features Gargantos, the giant one-eyed octopus, wreaking havoc on the streets of New York City, and Doctor Strange and Wong must fight the creature to save America Chavez. Luma’s Senior VFX Supervisor, Olivier Dumont, led the crew to deliver close to 270 shots that involved intricate creature work, digi doubles, crowds, and complex environments and effects.

Luma Pictures was tasked with defining the creature's behavior and movement, and the studio leaned into the inherent goofiness of the one-eyed monster, while ensuring that the creature looked as photorealistic as possible. The creature's design went through extensive exploration before a direction was chosen. Luma also designed the crowd, digi doubles, and destruction effects for the battle scene. In addition to Gargantos, Doctor Strange and Wong's sorcery was also given a redesign. Marvel wanted to show something different from what was seen in previous MCU films, and Luma was instrumental in delivering the new and exciting look of their magic. 

Creating the massive environment build of the New York City streets involved everything from matte paintings to projections to full 3D environments. Luma utilized Unreal Engine for post-visualisation of the New York Cityscape background —building a unique Unreal layout pipeline so the team could quickly lay out and visualize buildings that would later translate to full city builds.
