The Order of the Phoenix movie

Was that a mistake I spotted in The Order of the Phoenix movie? Though I never realised until I was reading The Deathly Hallows. There is a line in Hallows which states something like, “The scar on the back of his right hand started to burn,” but in the movie he writes his lines for Umbridge with his right hand, but the cuts appear on the back of his left hand.

Speaking of Umbridge, she was nowhere near toad-like enough as she needed to be. Otherwise this movie was good. One of the best things is that it was not too long. Yes, they cut a lot out (such as St Mungo’s), but it zipped along and didn’t get boring. So it gets the Blogwarts seal of approval; my favourite after The Prisoner of Azkaban.
