In WandaVision, Evan Peters is cast as a version of Wanda's brother Pietro, aka Peter, aka Quicksilver. The Quicksilver in the X-Men movies is generally considered a different character than Pietro Maximoff in the MCU, though both are versions of the same comic book character. Given that the same actor played Quicksilver in multiple X-Men movies, was the likeness of the character as portrayed by Evan Peters owned by Fox?
Did Marvel Studios need to get a license or permissions from Fox to use that character? Or does using the same actor playing a similar character not fall into using the likeness of that character?
