While the trailer shows considerably more of the story, it still leaves some mysteries unanswered. It doesn't show how Buzz becomes immortalized as a figurine in the Toy Story movies, or shed much light on other personas like Emperor Zurg.
The movie premieres in theaters on June 17th, with Chris Evans replacing Tim Allen as the voice of Buzz Lightyear. Sorry, folks, there won't be a prompt Disney+ launch this time. If there's anything that might coax people back into the real world, though, a spinoff of Pixar's best-known franchise might do the trick.
