Moon Knight was a little bit more hit-and-miss than we anticipated, and one of the main criticisms was the lack of costumed action throughout the course of the Disney+ series.
Unfortunately, Moon Knight proved to be something of a non-factor in his own show until the finale, and when he did appear, there was something not quite right about him. For whatever reason, many of the hero's scenes saw his costume brought to life primarily with visual effects, and they weren't always all that great (just look at the banner image above).
We have seen photos with actor Oscar Isaac "suited up," but it sounds like the actor actually spent relatively little time in the costume.
Talking to Defector, an anonymous VFX artist spoke about the meaning of "assets" in the world of special effects, with Moon Knight's costume being one that his company inherited. Apparently, Isaac was "nowhere" near any of the on-set footage of the character they worked on as they only had "a digitally costumed Moon Knight asset that had been passed onto them by another effects house."
While it made sense for Moon Knight's costume to be CG when it wrapped itself around Marc Spector's body, why it didn't then transition into a practical suit is hard to say. It's always possible that Isaac, like many other actors before him, wasn't interested in spending time wearing the outfit. We also can't discount the possibility that a tight production schedule played into the decision.
There's still no word on a Moon Knight season 2, so we don't know when or where the character will return.
Hopefully, that will give Marvel Studios the opportunity to either improve the Moon Knight costume VFX "asset" or find a way to make a practical version that works well on screen.
All six episodes of Moon Knight are now streaming on Disney+.
