The Girl in the Fireplace - S2-E7
Corrected entry: When the Doctor enters Renette's room for the first time, he pulls back the curtain and looks out of the window. We see that it is heavily snowing on the famous French cathedral of Notre Dame. It is impossible to see Notre Dame from the windows of the chateau de Versailles, as Notre Dame is in the centre of Paris and Versailles is on the outskirts.
The Girl in the Fireplace - S2-E7
Corrected entry: When Madame de Pompadour is walking in the gardens with her friend, the Doctor ducks down behind a pillar so he will not be seen. He puts his hands on the pillar but in the next shot they are gone, then they are back again.
Correction: Having just watched that scene, the Doctor's hands don't disappear when he's ducking behind the pillar. There are no continuity errors in the placement of his hands in the scene at all.
Correction: This scene does not occur at Versailles. When the doctor asks Reinette where she is she replies "Paris, of course." The fireplace is later moved to Versailles.
