Myka tells Pete about her younger sister Tracy, but in the pilot, she tells Pete that she is an only child.
When Peter tells Myka about his bad vibes about her going on the stage, she takes off her shoes. Later, when she decides to go on the stage, she leaves without ever putting her shoes back on.
When Myka is starting along the runway the previous model passes on her left. An instant later the model is past her but on the other side of the runway.
When the person walks up with the computer for the transfer they are holding it with one hand on the bottom and one hand on the top but in the next scene they are holding it by the sides.
Russian naming for women ends in 'a', so it would be Anya Verdikova, and Verdikov for son.
During the first scene, a castle is shown with titles stating that it is in Cardiff, Wales. However at the top of the castle rampart, there is a French flag, indicating the flag is in France, and not Wales. Yet a flag is not indicative of location; it's not impossible for a French person to own a Welsh castle.
When Perry 'whammies' Myka with the Camera he has got to the darkroom - fixing 2 different prints of Myka and the Elderly Woman - for those prints to swap ages and Myka to be affected. When Artie catches Perry, just double exposing Perry (on to Myka's image) causes the ages swap immediately - with the film still in the Camera. Artie explains then that the age-swap can be worked two ways.
Around mid season 2 we see on Arties computer screen that has both his names on it, that his surname is spelled "Neilsen", but the credits spell it as Artie Nielsen.
When Myka is knocked to the ground you can see the stone fly right by the camera for a split second from a previous take and then Pete comes and throws the stone to Myka.
Myka is wearing THE dress of the collection. There is no applause.
The solutions used to develop/fix photographic prints are water based. Would not ignite.
