That first big trailer for The Force Awakens was great, and we've established that anytime you cut another movie in the same style, the end result is just as great. So what happens when you recut Harry Potter with it? Perfection.
Jonny Holloway, a UK screenwriter and filmmaker has gone and taken Harry Potter and the Order of the Phoenix and put it together in the same style as the Force Awakens trailer. The result is pretty damn good, capturing the urgency of the film and all of its great visuals.
