These are a list of errors from Brickfilms (Lego Stop Motion) that i have found. I do the errors for very popular lego videos, if you want me to search a certain lego video for goofs/errors, just ask me in a comment. Note: Pictures are displayed in order of how the errors are described (Goof #1 = Goof Picture #1)
The Magic PortalEdit
This was the first Lego Stop Motion ever.
When the gate opens when the Monster is breaking through the wall, an area suddenly appears.
When Captain Paranoia is walking around when he is flushed out of the white world, two fingers appear for a split second.
Captain Paranoia's hat disappears in several scenes.
When El is getting electrocuted by the wires, a red beam above disappears, revealing a window.
When El enters the room containing the portal, the door that leads into the room says L17, meaning Level/Floor 17, but later when Pee is talking to El, they are in the same room, therefore the same level, but there is a sign that says L18 above.
When El is in the Maze World and looks at the pathway just before the Monster destroys the gate, you can see a lamp above.
Visible Object in the SkyEdit
After El escapes from the Monster, there appears to be a wire of some sort visible in the sky.
Disappearing White ClayEdit
In one scene in the real world, Pee walks past El and the Plasticene and some white clay remains where he walked but it quickly disappears.
