One of the last scenes sums up this movie pretty well. During the apostle's death scene, the camera cuts away from the apostle, who is clearly not talking, and they added in audio of her talking to the main character. Just to be clear, this was not meant as a psychic moment or a flash back of something she said previously. They filmed a scene where her character wasn't talking and then went back in post and edited in dialogue for her character, and it was EXTREMELY obvious that they did this.
