About ten months after we learned that Jon Favreau would be heading up a Star Wars series called “The Mandalorian” on Disney’s soon-to-launch streaming service Disney+, we have the first full trailer. It premiered this evening during the Disney+ panel at the D23 conference.

Everyone involved had stayed relatively hush-hush about the series until now, with only a couple of details mentioned with its announcement. We knew it takes place about five years after Return of the Jedi — so a few decades before Force Awakens. Favreau had also said that it follows “the travails of a lone gunfighter in the outer reaches of the galaxy” — which we later learned would be played by Pedro Pascal (perhaps best known as Oberyn Martell from Game of Thrones.)
