That's..not entirely true.
I would think they would've closed down Hogwarts Express for the opening, considering the ramp jump stunt that was done, they probably had to close it down for safety.
And, it's a specialty event. If we're going by that logic, then Transformers should've had Pyro as they had some on the rooftop of the structure for that opening.
If it was Fast and Furious, there'd also be a kickass tunnel effect, followed by a practical scene leading into a rather dull Musion scene and a copied and pasted version of the 360 scene. :tease:
