From today's MiceChat update:
"While those on-ride videos became Internet sensations accidentally, one element of the media events that fell totally flat was the faux hazmat scene themed to the Avengers that was artfully staged just past the ride near the Hollywood trolley station. No one attending the Thursday media party or the Friday $150 preview party cared about it, and Burbank’s plan for that hazmat scene to “go viral” failed completely. The goal was to give people a big hint about the new Avengers high tech coaster E Ticket now greenlit for the expansion pad just beyond the trolley station, which is an attraction Miceage Updates have been mentioning for over a year. When you try hard to make something go viral, it usually fails. The folks at those events were there to see the Guardians of the Galaxy, not the Avengers."
