Continuity mistake: Michael Bisping tackles the CIA agent and they begin a brawl in a room. There's a close-up on Donnie Yen looking at them, but in the next shot he's nowhere to be seen between the open doors - he appears only in a different shot a couple cuts later. (00:10:15)
Continuity mistake: When Pete is holding his hands out, as per Ego's instructions, the orientation of his hands changes. Initially, his thumbs are roughly at the top, but when the camera angle changes, they are at the side. No time has passed, and Ego didn't tell him to change anything.
Continuity mistake: In the mid-credits scene in Justice League vs. Teen Titans, Terra's hair was shoulder length and she had no freckles, but in this movie, she now has shorter hair and freckles.
