Here’s an interesting surprise, it seems that Jake Lockley speaking Spanish wasn’t something that was included in the script. According to producer Grant Curtis, it turns out that this was something that Oscar Isaac improvised during production. While it’s unclear if the character also speaks English with a different accent, it certainly highlights just how involved Oscar Isaac has been in the project.
It was all Oscar. That was not on the page. Oscar brought so many narrative elements to this show, both in front of the camera and behind. He’s a storyteller first and foremost, and that was just one of the many contributions he made to this series.Grant Curtis
There have been many theories that we’ve actually gotten a few glimpses of Lockley throughout the series’ run. In one moment while he is confronted by Dr. Crowley, we can see a bruised-up version of Marc that ends up getting quite violent as he grabs a pyramid. Yet, there were hints that this might not be the case either.
For now, we can only speculate as we await any sign of whatever the future has in store for Moon Knight moving forward. Isaac has said he’s open to tackling the character again if the right story presents itself. So, we’ll see what the future has in store for the character and fans once Marvel makes an official statement.
