Among all the rumored and confirmed cameos that Star Wars: The Last Jedi has said to have, Joseph Gordon-Levitt is a new name to the list, but he's honestly not all that surprising either. Gordon-Levitt has worked with Rian Johnson before on Looper, and Brick, two of Johnson's previous directorial efforts. The two clearly have a strong relationship. It's not known whether the actor went looking for the cameo or had it offered to him, but either way, seeing the connection makes sense.
While Rian Johnson confirmed that Joseph Gordon-Levitt would be in the film, and confirmed it would be a voice only role, that's where the information, according to Premiere Report (via StarWarsNewsNet), stopped. The fact that it's apparently a voice only role would seem to rule out a Stormtrooper cameo similar to the one that Daniel Craig had in Star Wars: The Force Awakens, but just about any sort of alien creature would be on the table. If we're going to put money on it, listen for Gordon-Levitt's voice during the scene that takes place in the casino city of Canto Bight. That sequence will likely be full of numerous different aliens with brief dialogue, it would make sense to include a cameo or two in there.
Joseph Gordon-Levitt's cameo comes on the heels of a few others that were recently confirmed for Star Wars: Episode VIII. English Princes Harry and William were confirmed, along with actor Tom Hardy, by John Boyega, who apparently simply got tired of being asked about the rumors and decided to let the cat out of the bag. Most of the cameos in Star Wars: The Force Awakens were successfully hidden until the film's release. All except for the one by Daniel Craig, though he vigorously denied he was doing it at the time. Now, the idea is apparently to let these details out, perhaps as a way of distracting us so we don't ask about more important things.
Still, we're guessing that there may, in fact, be even more cameos that they're not telling us about. There are so many people who grew up in love with Star Wars who are now celebrities that the line to add to their face or voice to the franchise probably goes on for miles. We'll find out for sure when Star Wars: The Last Jedi finally arrives December 15.
