Other mistake: In both the books and the movies, Harry's Invisibility Cloak can always be seen until it is worn. In Diagon Alley, just before the Gringott's break-in, Ron pulls out the cloak to cover Harry and Griphook, but it turns invisible before he puts it on them. Ron merely mimes the motion of covering them.
Other mistake: In Snape's memories, Trelawny's prophecy is the wrong one. If you listen closely you can hear her saying "master shall be reunited once more". That's the prophecy that she told Harry in PoA, not the first prophecy Snape half-overheard Trelawny telling Dumbledore.
Other mistake: In the final scene when Harry and Voldemort "connect" their wands, there is a close-up of Harry's face. Although the only light source seems to be the ball of fire between him and Voldemort, Harry's face is lit from his left.
Answer: Yes. According to J.K. Rowling in interviews, the curse Voldemort had cast on the Defense Against the Dark Arts position preventing any teacher lasting more than one year, was finally broken upon his death, and from then on any instructor lasted beyond twelve months.

In the movies it is never mentioned that Voldemort cursed the DADA post or even applied for this position.
It is mentioned in the books.
