I love this scene. Pity there's no audio, part of what makes this scene so awesome is Alan's voice.

I was touched by Minerva and Horace's pitiful looks. They look genuinely appalled by what's going on.

Amycus Carrow is really ugly. When I thought some considered Severus as ugly - they had not seen Amycus Carrow yet !

I love how Minerva pushes Harry aside - always ready to defend her lion cubs.

I noticed in that scene (I saw the movie already) that not a single time Severus attacked Minerva. He just defended himself, deflecting her spells, he never meant to harm and aware of his own skills as a duelist and power as a wizard, he prefered to flee, rather than kill or even wound someone, student or staff. Minerva can hold her turf fine too, she's a great duelist.

Pity there's no audio, Alan's voice is what gives the most tension in that scene. "NOW !" (1:41) He has such a perfect diction. A model.
