Visible crew/equipment: In the dinner scene in "Her" Excellency garden, right after Lamia breaks the egg in her hands, there's a cameraman's reflection on the metal jug held by Max.

Continuity: When Max is taking with Lamia, while she is sitting naked on a bed in the final part of the movie, Lamia's position changes between the shots. Her left elbow rests on her left knee when she's shown from behind, while her left knee is in front of her left arm when she's shown from front.

Visible crew/equipment: When Max, Albert and Lamia exit the underground and walk inside the tent with painted false landscape, there are regular rows of studio lights visible reflected in their helmets. They would immediately recognize that it's not a real world if the lights were there.

Plot hole: If the underground women really believed that Einstein and Copernicus were female, they wouldn't laugh at the quote of Marie Curie.

Revealing: As Max is climbing from the tree onto a wall surrounding the garden, the wall moves when Max puts his leg on it.
