Check out one post he made teasing his Star Wars appearance.
The biggest surprise to come out of Solo: A Star Wars Story was the reveal that Darth Maul was the secret bad guy behind the Crimson Dawn crime organization.
While Maul has been back for a while thanks to Star Wars cartoons, this was his first live action appearance since 1998.
Ray Park, the actor who physically plays Maul in The Phantom Menace, was brought back for Solo, and while these types of cameos are usually shrouded in secrecy, Park was pretty into teasing it on social media ahead of his ultimate appearance.
