Highly unlikely

A link on BuzzSugar took me to this article:

"Harry Potter fans are set to get a double treat in the film of the final story – and movie makers are set to double their money.

Crew working on the sixth Potter film, Harry Potter And The Half-Blood Prince, have been told J.K. Rowling's seventh novel, Harry Potter And The Deathly Hallows, will be released in two halves.

For film-makers Warner Bros, whose first five Potter films have made £2.5billion in box office receipts – more than any other movie series – it could mean a £500million bonus in ticket sales.

But sources insist the reason behind the two-movie plan is artistic rather than financial.

The books got progressively longer – the first, the Philosopher's Stone, had 223 pages while Deathly Hallows has 776 – and fans have complained chunks of later novels have been left out of films.

A film source said: "There's so much to fit that the view is the last movie should be in two halves. There is a huge battle when Harry, played by Daniel Radcliffe, takes on Voldemort that needs to be done really well."

And Ms Rowling points out on her website: "It is simply impossible to incorporate every storyline into a film under four hours long."

At Warner Bros, who are rumoured to be thinking of Oscars and a big-name director such as Steven Spielberg for the final film, a spokesman said:

"People are discussing all possibilities.""

I highly doubt this will happen--and please, if they can turn a Tolkien novel into a reasonable film, they can handle Harry Potter and the Deathly Hallows.
