Warner Bros. Quidditch Ball Enters Diagon Alley

This CGI advertisement features a giant Quidditch ball flying out of the screen and entering Diagon Alley. The scene initially shows Diagon Alley with a train passing in the foreground.

As the Quidditch ball enters Diagon Alley, a warped area appears at its point of entry, creating the illusion of the ball passing through a portal.
