Marvel Studios' Visual Development Supervisor and concept artist Andy Park just offered fans a behind-the-scenes look at Thor: Ragnarok in a series of VFX videos. In five separate clips, Park revealed the digital work that went into scenes such as Thor's opening fight against the dragon on Muspelheim, his capture on Sakaar, his first encounter with Korg, his final battle on the Bifrost and Hela's massacre of the Valkyries.

Each video plays a full scene that toggles between various stages of development. From the blue screen stage to the final product, the snippets show just how much of the scenes were created by VFX artists. They also offer a fun glimpse at pre-VFX characters like Taika Waititi's Korg and his blade-happy sidekick Miek.
