Emma Watson and Harry Potter co-stars to re-shoot crucial final Deathly Hallows scenes

When Emma Watson chopped off all her hair into a daring pixie crop in August, it was a sign that she had finally left Hermione behind.

But now it seems the makeover was a little premature, as she and her Harry Potter co-stars are called back to re-shoot scenes for Deathly Hallows: Part 2 over Christmas.

The 20-year-old described in a recent interview how she and co-stars Daniel Radcliffe and Rupert Grint broke down on the final day of filming.I cracked first, obviously being the girl,' she told the Daily Mail last month. 'Dan cracked second, then Rupert - we were all in floods of tears.'

But even though they were sad to leave behind something that had defined their childhoods, the three stars have all expressed relief that it was over.

So they may have been a little irritated to have to return to Platform 9 and 3/4 to re-shoot the important closing scenes - which take place 19 years in the future.

As fans of the books remember, Harry, Ron, and Hermione, as well as Ron's sister Ginny, return to King's Cross station to send their own children off to Hogwarts for their first year of school.
