Director Rian Johnson revealed the news during a press conference in Japan last weekend, saying, "I think this is OK to say."
He went on to describe what Joseph will be doing in the movie: "My very good friend, the actor Joseph Gordon-Levitt, who is in a movie I made called Looper, he does a cameo as a voice of an alien in thea very brief, little thing but it’s fun. And if you watch the movie and hear, maybe you’ll pick out Joe’s voice in the movie. It’s the first time I’m revealing that!"
The highly anticipated film will be hitting theaters on December 15, 2017. ~Alexandra Heilbron
