Disney teases 'Star Wars,' 'Frozen 2,' more at convention

At the Walt Disney Company's biannual D23 convention, a faint image of the "Star Wars" character Emperor Palpatine in the background of a new poster can cause as much of a stir as actual appearances from movie stars such as Angelina Jolie and Dwayne Johnson. But that's no surprise for the most powerful studio in the world, whose characters are stars as big, if not bigger, than the A-listers playing them — at least for the people attending the company's fan convention.
