Having the full Dudley’s redemption full scene would be really cool.
Aside from making it look good, I would hope you’re still able to make it fit in with the cool opening montage.
I’m not sure how well that would work, given that the scene would be longer, but maybe some parts of it (such as walking could be trimmed).It would be, but it could affect the pacing of the opening montage.
I don’t know, I feel like a few extra quick dialogue scenes and more shots of the handshake could work out.
I’m currently updating my own extended editions. In mine, I had Dudley tell Harry that he didn’t think he was “a waste of space,” the two exchange a melancholy glance and down at their handshake, and Harry says “See you, Big D” as Dudley walks off.
