This is not Clara!

Jeremy and I were watching Dr Who last night, when we spotted an odd shot. Jenna obviously did not make the filming that day, so the director just used someone else and then the editor just let the scene through!

It did not look like Clara to us and we thought she was a bit tall!

Did they not realise that us and everyone else with a TiVo or Sky box would rewind and freeze frame to spot the substitution!
