Goodnight Mommy
Elias is a sweet little boy, and the plot line of Goodnight Mommy is all the more tragic for it. His brother actually died in an accident! This means that Lukas is not really in the movie. He had not been alive for the duration of the film. The scenes in which he appears are only hallucinations.
Now You See Me
Who would have guessed that the FBI is actually the good guy in this story? Dylan is with the Four Horseman the entire time for a good reason. You see, he is the one who came up with the entire heist! Now you see you him, and now you don’t… Nobody saw that plot twist coming!
