While "Star Wars: Episode VIII" won't open in theaters until December 15, 2017, we're already getting a few clues from the movie's director and actors on social media.

We already know that filming has begun on the new Star Wars movie after Director Rian Johnson shared a brief new scene featuring Luke Skywalker (Mark Hamill) and Rey (Daisy Ridley).

"Star Wars: Episode VIII" began principal photography at Pinewood Studios in London on Monday, and actors including Hamill and Carrie Fisher have retued to the set, with their beloved pets.

On February 19, Fisher tweeted an emoji-laden message with a photo of her lovable dog Gary lounging on her chair.
