That Special Effect at the End of Avengers: Infinity War Was Based on One Specific Infinity Stone

The power of the whole Infinity Gauntlet was needed to fulfill Thanos’s master plan, but if the special effects are any indication, it was one stone in particular that did the job.

In a wide-ranging interview with Inverse, Infinity War VFX Supervisor Dan DeLeeuw discussed the design behind the infamous dissolve-to-dust special effect used to dramatize Thanos’s victory at the end of Infinity War, saying that it was based particularly on the Power Stone, one of the six Infinity Stones Thanos had gathered by that point.

“The Power Stone was blipping them out of existence,” DeLeeuw said. This decision, which has both narrative implications as well as design ones, was made after a lot of back and forth with regards to what effect would be best. What would each stone look like, erasing characters? Eventually, they settled on just one stone.

“We had concept art combining all those things, and it was getting too busy,” he said. “It became too complicated. It was stepping on what the actors were doing. So it became ‘body turns to ash.’ We peeled away all those layers and focused on that one [Power Stone], deciding how quickly it would consume someone, what pattern it would consume them.”

Whether this means that only the Power Stone did the work of erasing half the universe, or if the other stones helped out (maybe the Space Stone augmenting its power across large distances, or the Reality Stone indexing all of reality or something), is up for lore nerds and fans to figure out. After all, he had to have collected all six for a reason, right?

The whole interview over at Inverse is worth reading for a few more tidbits about how the internet’s favorite way to die came to be. Avengers: Infinity War is out now on digital and Blu-ray.

All six Stones were needed to erase half the universe: each played a part in the process, it couldn’t have been done if even one of the Stones was missing. The roles played by the stones:

  • Space: Affect the entire universe, not just the area near Thanos
  • Time: Affect the whole universe at once, relativity be damned
  • Soul: Target living beings, not inanimate objects
  • Reality: Fundamentally alter reality and make the change permanent, even after Thanos stops concentrating on it
  • Mind: Coordinate the Stones and their effects, because even Thanos doesn’t have the cognition to visualize every single living being in the universe all at once
  • Power: Provide the juice to make such a wide-ranging effect possible

As for why the Power Stone dominated the visual, I would guess because the other Stones were all being used for other things, so the actual effect, “erasing people,” was taken over by whatever was left: the Power Stone.
