Continuity mistake: During the introduction, the snake tries to get away from someone who is supposedly Blackadder. He gets the snake. It's head is above a black tile. There is then a close-up of the snake, Blackadder wags his finger at it. It is now above a white tile.
Cygnus! Hyogen no senshi - S1-E3
Continuity mistake: In the sequence where Hyoga defeats Ichi breaking his armor with the extreme cold of his Diamond Dust, in one intermediate bit the coloring artist did something wrong and didn't fill the leg with the green color of the suit, but rather the pale skin color of Ichi's. So, for a second it seems that Ichi is in his underwear, or Hyoga froze his pants off. (00:21:05)
Visible crew/equipment: Right after Mary Jo tells Anthony to eat her shorts, when the camera points at him, you can see the edge of the set and several people behind it. (00:08:15)

Visible crew/equipment: When Mark Harris shows Matlock into his office, the actors' three tape marks (one T-mark) are visible on the carpet behind the chair, and at the bottom of the screen.
