Joseph Gordon-Levitt has worked with director Rian Johnson on three movies (Brick, The Brothers Bloom, and Looper), so it only stood to reason that Gordon-Levitt would get to be included in the Johnson-directed Star Wars: The Last Jedi.
Spoilers ahead for Star Wars: The Last Jedi!
His name pops up in the end credits and everything; he voices a character named Slowen Lo. Fans, according to Entertainment Weekly, correctly guessed that Gordon-Levitt's cameo is during the casino scenes in Canto Bight. However, it is not the small, drunken alien who shoves tokens into BB-8, which some believe is actually Mark Hamill's second role in the movie.
EW confirmed that the actor appears as the concerned, "catfish-looking" alien with a "Foghorn Leghorn" cadence who tells the Canto Bight authorities that he told Rey and Finn they couldn't park on the beach. He shows up just as the pair are about to approach the master code breaker that Maz told them about. Slowen blocks their way and the two are arrested and locked up, which causes their path to align with that of Benicio del Toro's DJ. In addition, the character's name was inspired by the 1986 Beastie Boys song "Slow and Low."
For some of the character's backstory, you need to check out the movie's Visual Dictionary. It says that Slowen Lo made a fortune by selling driftwood sculptures and was able to buy a beachside residence with the money. And despite the fact that Rose and Finn arrived in the evening, Mr. Lo's eyes didnt fail him as he's got surgically-implanted lenses to compensate for his failing sight.
It makes the most sense that Gordon-Levitt's cameo would be featured during the casino sequences, because there were 200 extras and so many diverse aliens and patrons featured. You'd probably have to watch The Last Jedi at least twice in order to take in all the detail of the fancier take on the Mos Eisley cantina.
In any case, Gordon-Levitt should have felt right at home since he is a Star Wars super fan, having showed up The Last Jedi's premiere in full Yoda attire. At 5' 9'', he is a bit tall for the wizened old Jedi master, but we're a bit disappointed that he didn't walk on his knees the entire time, as Mel Brooks did in Spaceballs.
Representatives for Mr. Gordon-Levitt did not immediately respond to SYFY WIRE's request for comment.
