On another post of mine someone replied with a Twitter link showing these stills from the next movie to be shown at 2018's RC, about Jonah.
Not only is it VERY early for any leaks to be coming from the convention, but the images appear to be taken off of another screen, which leads me to believe someone behind the scenes leaked this against explicit directions.
Also . . . Where's the AGM video leak by now? 🤔
