Episode 14 in the 2011 series covers the last two pages of chapter 23 through chapter 25. It corresponds to episode 21 in the 1999 series. To put pacing into perspective, keep in mind that the 1999 series would have only covered up to Kurapika vs. Majitani at this point. Also, despite both series beginning in the month of October (the 2011 series started two weeks before the 1999 series did, though), we're progressing much faster. We wouldn't have seen this part until mid-March in the original. Not so necessarily say this is a bad thing, especially considering that the 1999 series marathons pretty well. I just feel that it is important for the comparisons to detail context as well.
The opening scene in the 1999 series is scripted almost entirely differently. While I transcribed the dialogue mostly from the Viz subtitles, a lot of their translations are liberal for the sake of flow. But I also translated several of the lines myself in order to convey nuance/indicate if the script reused specific words or lines.
Lippo (1999): We now have only the Fourth Phase and the Last Phase to go in this Hunter Exam. About the Fourth Phase... I'd like everyone to draw lots.
Everyone: "Lots?" "What now? Lots?"
Lippo: "There are as many cards in this box as the remaining applicants. You'll each choose one in the order in which you escaped from the Trick Tower."
Khara: "And with that, Mr. Hisoka, please go ahead~!"
Hisoka, Gittarackur, Hanzo, and Sommy draw their lots.
Lippo: "Now then, the card you just picked will have a number. And those numbers correspond with the remaining applicants' ID numbers. And this drawing has just determined...the hunter and the hunted.
Leorio: "The hunter and the hunted?"
Gon: "What does that mean?"
Lippo: "In short, the objective of the Fourth Phase is: 'Stealing each other's ID badges.'"
Imori: "Huh?!"
Hanzo smirks.
Lippo: "And the applicant whose badge ID number corresponds with the card you've picked...(Lippo points to the sky and then to the audience) is your target!
Fourth Phase × Forty-Four × Number of Death
Khara: "We've recorded the number each of you have picked! We do not mind if you wish to dispose of them."
Lippo: "Heh heh...As I was saying earlier...Your objective is to collect the ID badge off of your target. In order to pass this phase, you'll need six points."
Hanzo: "'Six points...?' What do you mean by that?"
Lippo: "During the Fourth Phase, each badge is worth a certain number of points. That is to say, the number tag of your target is worth... 3 points!"
Imori gasps, Hanzo smirks.
Lippo: "Your own number badge is also worth... three points! In other words, if you can steal your target's badge and manage to protect your own badge, you will pass the Fourth Phase. And by the way, all other applicants' badges are worth one point. Of course, I don't care if you get the six points you need that way. You'll be staying on Zevil Island for one week. The entire island is your playing field. It doesn't matter what methods you use, collect the six points. Well then, I'll leave the rest to Khara."
Khara: "Yes! I have some wonderful news for everyone here! Everyone here has been granted an unconditional invitation to take part in the First Phase of the Hunter Exam next year! If you weren't able to make it this year, please try again next year, ye~s? ... So gloomy... Well then! Everyone, the trip to Zevil Island will take about two hours, so please relax and enjoy yourselves."
Lippo: "You may know who you're hunting, but you have no idea who's hunting you. It could be someone standing next to you, like your friend. Fufufu... The battle has begun."
I won't bother transcribing the 2011 series' version because it's more likely for you all to watch it. Just know that aside from extending the scene in which everyone draws lots to include Gittarackur, Pokkle, Gon, and Killua (including a 5 sec scene of Gon asking Killua a question about the manhunt/Leorio making a comment about drawing lots with style), the scripting and direction is just about the exact same as it is in the manga. None of Lippo's lines are changed, and the sequence matches.
In the 1999 series, Khara accompanies Lippo to have the contestants draw lots. In the 2011 series/manga, Lippo and the other unnamed proctor do it.
There isn't a removable seal on the number lots in the manga or 1999 series, but there is one in the 2011 series.
Lippo. His gestures are more natural in the manga/2011 series. In the 1999 series, after making a gesture, he always returns his hands behind his back. Also, the way he holds up six fingers matches the manga's blocking in the 2011 series.
The 2011 series adds a line in which Imori asks for clarification about the methods one can use to steal each other's number badges. Lippo clarifies with the line "Of course, you are free to use whatever methods possible to steal your target's badge. And let me say, I don't mind if you kill your target and steal the badge off his corpse." I think it's funny that both versions depict Imori's cowardice, since his catchphrase clearly contradicts his actions.
The 1999 series turns the Fourth Phase into a moral issue. There's a filler scene in which Kurapika and Leorio discuss the manhunt. Kurapika seems angry that it's a manhunt despite not having a problem with it during the phase.
Tonpa approaches the pair again and introduces every character that plays a part in the Fourth Phase. The other side characters aren't really discussed because they were introduced in a three-episode long filler (episodes 18-20). It helped to flesh out some of the top 24.
The manga introduces the top 24 on its cover page. The 2011 series has a kind of long scene in which it shows every candidates' faces.
Also: the boats they're on are different. The 1999 series has the candidates take a battleship to Zevil Island, whereas the manga and 2011 series has a smaller boat do so. However, once the applicants
Gon and Killua's conversation here was one of my favorite moments in the series while I was only three volumes into it. It's a bit different between all three versions. I really liked the first panel of Gon sitting on the ship in the manga because of how spacious it is. The clouds, the people in the background. The fact that you can't see his expression.
In the manga/2011 series, Gon sit below the railing of their boat. In the 1999 series, they sit off the edge of the battleship. Compare their gestures/blocking to those the manga. This scene is very well done in all three versions, I felt.
Gon in the manga/2011 version is trembling with anticiption and Killua notices. Gon doesn't tremble in the 1999 series. Killua doesn't ride away on his skateboard in the 2011 series--he carries it instead.
Zevil Island. The 1999 series forgets to draw in the body of water located on the island.
The 1999 series changes one of Khara's lines once they reach Zevil Island.
Khara (1999): "After one week, please bring six points worth of plates and return back to this place."
Khara (2011/Manga): "You will stay on this island for exactly one week. During this time, you must please amass six points and return back to this place!"
When disembarking from the ship, in the 1999 series, Hemotropic Butterflies flutter around Hisoka's hidden wound and Gon notices. The 1999 series jumps straight to Gon's turn to disembark instead of showing Agon, Imori, and Killua disembark as well. The 2011 series shows Gittarackur, Hanzo, Agon, Shishito, Imori, Kurapika, and Killua disembark.
The 2011 series cuts out the scene in the manga when Gon first arrives and almost catches Geretta lurking in the shadows. He still stalks Gon in the 2011 series, but you don't see the scene as it was in the manga. This scene is in the 1999 series.
Geretta: "That was close. The kid's got good senses. I guess I'll take my time hunting him."
