Revealing mistake: Just after Proxima Midnight and Corvus Glaive land in the train station, there is a wide shot where they begin approaching Wanda and Vision. In the wide shot, their shadows do not appear to match up with each other, despite being under the same lighting. Proxima Midnight's shadow is positioned in front of her and is quite heavy, but Corvus Glaive's shadow is positioned more to his left and is much lighter than Proxima's. (00:40:20)
Revealing mistake: When Chewy puts his hand on Han's shoulder at the end, Joonas Suotamo's finger is visible through the fur.
Revealing mistake: When Orm presents the weapons to Manta as a water hologram, Manta walks right through the hologram with half of his body. This arm passes through the hologram made of water and even makes a splash sound. However, there is not a single drop of water on Manta's completely dry clothing after this.
Revealing mistake: Vera types "Nico Lasarte - Murdered - 1989" into a web browser. When she clicks the search button and the screen changes to list the search results, Vera's position in the frame can be seen shifting on-screen, revealing that the shot of the search bar and the shot of the search results were two separate shots merged together.

Revealing mistake: Most of the car scenes entailed rain on the windows even though it otherwise had not been and was not raining, indicating the scenes were filmed on a rainy day. For example: Mary driving home; picking up Todd to go to the funeral; driving home from the church; driving back from rock climbing; and, Faith's car when she got to Luke's house.
