The 19-years-later makeup is famously terrible. Rickman, Watson, and Radcliffe look like they’re wearing Halloween masks. The fix: With today’s deepfake and VFX technology, a special edition could digitally de-age everyone to realistic 37-year-olds. No more middle-aged wigs.
During the final battle, when Voldemort’s forces are overwhelming the castle, the dragon — now partially healed, bearing scars but free — returns. It does not attack every Death Eater indiscriminately, but specifically targets those wearing Gringotts guard uniforms or those who tormented it. This creates a full-circle moment: the magical world’s oppressed creatures rise not for Harry, but for their own liberation, indirectly aiding the Order. harry+potter+and+the+deathly+hallows+part+2+20+fix
The film cuts away from Professor McGonagall confronting Snape. We see her cast a single flame spell, then Snape flees. In the book, she is a ferocious dueler, sending daggers of fire while being protected by suits of armor. The fix: A 45-second extended duel where McGonagall nearly corners Snape before he leaps from a window. It would be a show-stealing moment for Maggie Smith.
