Synopsis:
In New York, mysterious radioactive ooze has mutated four sewer turtles into talking, upright-walking, crime-fighting ninjas. The intrepid heroes -- Leonardo (Brian Tochi), Michelangelo (Robbie Rist), Donatello (Corey Feldman), and Raphael (Josh Pais) -- are trained in the Ninjutsu arts by their rat sensei, Splinter. When a villainous rogue ninja, known only as The Shredder, arrives, spreading lawlessness throughout the city, it's up to these turtle brothers to stop him.
Intentions:
To celebrate the release of Mutant Mayhem, this edit means to fix as many of this film’s production and continuity goofs as possible. Patching a few holes in one of the greatest movies ever made… plus a few other things. Not a single shot is cut in this edit. I wouldn’t dare.
Change List:
Added the trailer shot of the turtles rising from the water, placing the shot (mostly) according to the comic adaptation. Edited it so we see all four turtles come out of the water instead of just two, color-corrected, and added sfx. (0:03:17)
Added the film's promotional logo in place of the 87’ logo that was originally used (0:05:35)
Added Risinger Productions title card (1:33:32)
Fixed goofs:
Recolored Leo, Mikey, and Don’s white knee-socks green to match the rest of their bodies (0:05:38)
Fixed a double mouth (0:05:47)
Removed the stuntman’s arm swinging in while Donnie is skateboarding (0:09:25)
I never liked the compositing on Shredder’s throwing knife into the TV screen, so I changed the look of the handle a bit and added a bit more interactivity. Now the knife levels out in the air more like a real no-spin throw, and it has a light flicker from the TV. The crack in the TV screen also expands for a few frames. (0:18:14)
Removed the cameraman's head from the mirror (0:30:14)
Slightly adjusted the audio timing of Raph throwing his Sai by Donnie’s crotch (0:37:46)
Cropped out the kneeling production assistant during Leo’s fight with Raph. I also cropped the next shot slightly to keep framing consistent (0:38:22)
Redubbed Donnie with audio of Corey Feldman from TMNT 3 when he uses Leo’s voice for kiais during a fight (0:44:10)
Fixed the infamous Donatello double mouth gaff (0:56:30)
Obscured Mikey’s chucks while he’s screaming “Splinter” in Raph’s voice. This was originally supposed to be Mikey but was changed to Raph in post (I’m simplifying a bit, but that’s the gist). (0:56:47)
Removed the wires hanging from Raphael’s shell in one shot (0:59:44)
Changed the fire Splinter comes out of to 100% blue instead of two separate pieces of orange and blue fire (1:00:23)
Fixed another double mouth (1:04:17)
Fixed Donnie using the wrong voice for kiais again (why is this always happening to Don?) (1:13:47)
Fixed two more double mouthes (1:17:20 and 1:17:38)
Obscured the guards of Raphael’s sai. They should be Leo’s katana in this shot. (1:21:16)
Fixed the order of the shots in which Splinter drops Shredder (1:23:27)
Slightly trimmed a shot of Shredder falling (1:23:28)
Fixed another Donnie double mouth (1:27:41)
