Visible crew/equipment: At the very start, Zack hands Billy some glasses which he puts on. They reflect the stage light in front of them perfectly. (00:01:10)
Revealing mistake: When the Dragonzord returns to the sea, the shot is reversed. Watch the water. (00:09:30)
Visible crew/equipment: Just as the Rangers find a way to defeat Lord Zed's putties, we see a camera shot circulating the rangers. Pay attention and you will see that there is one shadow on the ground that doesn't move. Clearly from a member of the film crew. (00:16:40)
Revealing mistake: When Rita is shrunk and put into her travelling vessel, the shrunken Rita is a very bad model. (00:12:20)
The Trouble with Shellshock - S1-E22
Character mistake: About halfway through the episode, we see Billy, Zack and Kimberly are frozen because of Shell-shock. Towards the end when Jason and Tommy are in the Zords fighting Shell-shock, the Yellow Ranger comes running with the flowers that unfreeze the Rangers and Zords. The Yellow Ranger yells "Jason, Billy, I have the Diandra flower!" She should have yelled Tommy's name instead of Billy since we know Billy is frozen and that Tommy is the one helping Jason fight Shell-shock.
Suggested correction: She doesn't know that. She was sent running after they were frozen.
Continuity mistake: At the start, Kim falls out of bed and her alarm clock is at an angle to the edge of the bedside table. Camera cuts and it's parallel. (00:01:30)
Island of Illusion (1) - S1-E28
Revealing mistake: When the Putty patrol first attacks the Rangers, we see Kim jump and do a split kick on 2 Putties. However, she only connects with one but both fly back as though hit. (00:06:55)
Continuity mistake: The Rangers form the megazord, followed by the ultra mega zord. As soon as the wheel is destroyed, the ultra megazord has vanished, to be replaced by the standard megazord. (00:15:25)
Continuity mistake: Tommy has rope tied around his wrists when captured by the Puttys. When he breaks free, the rope breaks between the two wrists. However the knots and loops around his wrist vanish instantly. (00:12:15)
Revealing mistake: When Frankenstein throws the chain around megazord and lifts the megazord, wires can be seen lifting the megazord. (00:14:35)
Continuity mistake: Tommy goes to hit the spider on Zack's back with the blue folder, and does so. However as the camera cuts the folder vanishes. (00:02:25)
The Trouble with Shellshock - S1-E22
Revealing mistake: When Trinni is on top of Shellshock, we see him fall down and it is a model of the yellow ranger on Shellshock's head. (00:16:10)
Green With Evil (1): Out of Control - S1-E17
Revealing mistake: Goldar smashes some rocks that bounce around and act a lot like polystyrene. (00:15:00)
Green With Evil (1): Out of Control - S1-E17
Continuity mistake: Tommy throws putty onto some boxes and takes a stance with his arms raised. Camera cuts and his position has changed completely. (00:06:45)
Continuity mistake: When the Rangers first appear against Genie, he shoots rods at the rangers which stick in the ground, he then fires a string type substance at them. However the rods have disappeared. (00:11:40)
Other mistake: In various episodes we see Alpha working in the command centre. When we see him pressing buttons however, they are almost always the same buttons being pressed, regardless of the intent.
Continuity mistake: When the Red Ranger is being held by the giant monster, his right arm goes from trapped to free and back between shots. (00:16:20)
Continuity mistake: At the start, the blue mixture in the "cake-o-matic" appears instantly. (00:00:10)
