This question already has an answer here:
In Spider-Man: Homecoming, Ned has a LEGO Death Star. Additionally, in Captain America: Civil War, Peter references The Empire Strikes Back. This means that Star Wars exists in the MCU.
One example of a Star Wars actor? Samuel L. Jackson, who plays Mace Windu. S.L.J also plays Nick Fury in the MCU. So who plays Mace Windu in the MCU? Does Nick Fury play them? Does Samuel L. Jackson exist in the MCU, and play Mace Windu? If so, do people mention how Nick Fury and Samuel L. Jackson look identical?
