ThisRogue Onepreview, courtesy ofLucasFilm, offers a number of exciting revelations, including the confirmation ofWarwick Davis' involvement in this spinoff. The actor started his career by playing the iconic Ewok Wicket inStar Wars: Episode VI - Return of the Jedi, and he also played a number of characters inStar Wars: Episode I - The Phantom Menaceand he returned for last year’sStar Wars: The Force Awakensas Wollivan, who was seen in Maz Kanata’s (Lupita Nyong’o) castle. We don’t know for sure if he’s returning as Wollivan, or playing a new character, but this video also possibly teased Maz Kanata’s inclusion as well.

At the 1:46 mark of the video below, there is a montage of quick shots with several different characters, including one which appears to be the partially-obscured face ofLupita Nyong’o. We learned inStar Wars: The Force AwakensthatMaz Kanatais over 1,000 years old when we meet her inStar Wars: The Force Awakens, so it’s certainly possible she could surface in this movie. Hopefully we’ll get confirmation about whether or not this character is in fact Maz Kanata in the near future.

Rogue One: A Star Wars Storyis a prequel movie that takes place in the time between the events ofRevenge of the SithandA New Hopeand tells the story of how the Rebels got their hands on the plans for the Empire’s planet destroying weapon, theDeath Star.
