While some rumors have indicated that del Toro would be playing a villain, and the all black look certainly makes him sound like he looks similar to Kylo Ren, MSW says that the other characters in the film don’t treat him like a villain, at least not initially.
While this is all still rumor, Making Star Wars is correct more often than not when it comes to those rumors.
According to them, Benicio del Toro is playing a “man in black.”
It’s believed he may appear on a casino set which the site recently revealed will be part of the film.
