You saw the post on his Instagram account several days ago that featured Woody Harrelson wearing a blue t-shirt with the Star Wars: Solo logo on the left-front chest. Immediately we all assumed this was an official crew shirt for the untitled young Han Solo standalone film.

Sure enough, Harrelson confirmed during his recent guest appearance on The Late Show With Stephen Colbert that “Solo” is the working title for the film, which is being directed by Ron Howard.

You can fast forward to the 3:00 mark of the YouTube video below to hear the portion where Harrelson confirms the working title. Here’s hoping we get the official title for the film from Lucasfilm this weekend during D23 Expo.
