According to comicbook.com, Richard E. Grant has yet to reveal what character he'll be playing in Star Wars: Episode IX.
However, he recently teased that, upon learning the character's identity from Director J.J. Abrams, his whole world changed.
[I was] surrounded by all this Star Wars memorabilia going back to 1977. And within about two seconds, [Abrams] said, ?Are you gonna do it or not??
And I said, ?Do what?? Then he described the part, and I think he told me what my name was, at which point the room went upside down.
