They’ll have to do it slo mo.
Half the people reading the book didn’t pick up on where Longbottom got the sword from.
So, they’ll have to make a point of emphasizing that in the movie for us all to enjoy Nevil’s triumph.
That's why I made a point not to speed-read this book. It took me five days instead of five hours. And as it was, I still skimmed back a couple of times. I missed Lucius Malfoy's wand exploding and I wanted to reread the letter when we found the second page.
