Insane Polyjuice Potion Plot Hole in Harry Potter
The Harry Potter movies have had many inconsistencies, but there is one Polyjuice Potion fact that truly doesn't make sense!
Have you ever wondered why the Polyjuice Potion's effects vary from movie to movie? One fan has compiled everything that we know (and should have noticed before, but didn't) about this mystical concoction.
In the second movie, Harry and Ron change into Crabbe and Goyle, but they keep their own voices and possibly even their eyesight.
It takes effort on their part to make their voices sound more like the people they've turned into.
Plus, they run into Malfoy, who comments on "Goyle's" wearing glasses, which could mean that Harry can't see without them, even under the effects of the potion.
Or it could be that Harry simply forgets to take them off…
In the fourth movie, Barty Crouch Jr. spends the entire year disguised as Moody, and his voice, eyesight (or lack thereof), and the rest of his body change as well.
Is it because the writers didn't think things through before, or is Barty just better at Potions than Hermione? Unclear.
In the seventh movie, when some of the Order of the Phoenix members take the Polyjuice Potion to become Harry, Hermione makes a remark about Harry's awful eyesight (seemingly she now has Harry's).
Although all the characters retain their own voices, so in this instance, the effect is different again.
The question is – is Hermione saying what she is saying because she can't see as Harry until she puts his glasses on (as she gets Harry's eyesight), or because she can't see with the glasses on (as she still has her own eyesight)?
To make your brain go boom even more, in the last movie, Hermione turns into Bellatrix (voice and all).
Some fans say that she might have just gotten better at potions since the second year, and that's why her voice changes.
That seems like a good theory, but Hermione actually isn't the one who makes the potion in this case – she uses the last of Mad-Eye's supplies.
In the books, the Polyjuice Potion works the same way every time, but the movies have created so many questions without answers.
All we can do is rely on fan theories for some kind of explanation…
