Other mistake: In the opening of this first series dedicated to Lupin, Fujiko Mine is riding a motorbike with the poorly romanized brand "RUPIN III"
Is Lupin Burning... ?! - S1-E1
Other mistake: The logo of the evil organization, Scorpion, contains just a little misspelling. It's missing the R. (00:02:50)
Is Lupin Burning... ?! - S1-E1
Other mistake: When the race begins, Lupin goes past two number 10 cars. (00:06:05)
Is Lupin Burning... ?! - S1-E1
Other mistake: Jackie Stewart's car has a nice "DNLOP" logo (it's not a copyright issue, there are plenty other "Dunlop" logos with the correct spelling throughout the episode). (00:07:00)
Is Lupin Burning... ?! - S1-E1
Other mistake: When Lupin spins out of the oil patch, the "4" on the front of his car (on the arrow) disappears. The number changes also font and position several times throughout the episode. (00:09:40)
The Man They Called a Magician - S1-E2
Other mistake: In his training at the end, Jigen shoots over a dozen times with his revolver without reloading. (00:21:20)
The Man They Called a Magician - S1-E2
Other mistake: Despite falling unconscious at the bottom of the sea in his car and being rescued by Jigen, with Pycal within range since he got out of the car at the last moment, somehow Lupin gets to Pycal's home before he does, setting up a bunch of tricks in advance too.
The Man They Called a Magician - S1-E2
Other mistake: Lupin uses the three projectors to show Pycal the formula. To work, the projectors must carry one slide each, but then it turns out that Lupin had all three in hand the whole time.
Farewell My Beloved Witch - S1-E3
Other mistake: Lupin shoots a rocket from the plane, but in close-up you can see the flowers hit by a flamethrower stream. (00:17:45)
Farewell My Beloved Witch - S1-E3
Other mistake: The professor gets killed by Stern's machine gun, but he was inside the plane and the plane suffers not a single bit of damage. A stray bullet can go anywhere, but at least one of the other bullets should have hit the fuselage.
Farewell My Beloved Witch - S1-E3
Other mistake: In the first part of the episode, the Third Sun is purple when in the hand of the characters in close-up, and pink in the field. Different shades of pink, some quite dark, but never the same shade as the close-ups or even close.
