Continuity mistake: In the final battle, Lin Mi Sheng has her hair pinned up in a French twist. Her hair changes very frequently between shots and combat sequences. Sometimes it switches from a French twist to a slick chignon.
Plot hole: At the end of the film, we see Nick Fowler is now in the job originally held by Larry Marks before he was killed. We know Larry was corrupt and that he admitted in front of numerous agents that he had identified Nick's body. Surely, there is no way the CIA would allow Nick back, let alone in a leadership role, without questioning why Larry would lie about Nick being dead. That alone would raise serious suspicions about them both, but we're expected to believe he walked right back in?
