Well, you can't keep a good thing down, right?

With The Hobbit: Battle of the Five Armies nearing our cinema screens, it looks like we've reached the end of Middle-Earth's time.

Then again, maybe not.

Ian McKellen was speaking at the premiere and explained that Jackson initially drew a line under Tolkien's work at the end of Return of the King.

"Here we are, 13 years later. So I don't believe this is the end of the journey," McKellen said.

There is, of course, The Silmarillion still left to adapt and Tolkien has a wealth of unpublished material and short stories set in Middle-Earth that could easily be turned into feature films.

That said, the previous two Hobbit films haven't wowed critics in the same way the original trailer - so is it worth Jackson revisiting it again?
