Taking in more than .3bn. at the international box office and becoming the highest-grossing film of 2011, and the third-highest of all time (unadjusted for inflation), Harry Potter and the Deathly Hallows – Part 2 was a magnificent end to what has become the most successful film franchise ever.

Concept artist Andrei Riabovitchev, via Collider, has released some impressive new concept images for the film that show an earlier visualisation of how Voldemort (played by Ralph Fiennes) could have died, as well as a few close-ups of the giants’ heads.

Harry Potter and the Deathly Hallows – Part 2 was released in cinemas in the height of last summer, and took more than a 400% profit from a $250m. budget, which, as you can imagine, almost never happens.

It was released on DVD and Blu-Ray at the end of last year, and as you may be aware already, may not be around for long, because Warner Bros. announced that they would stop production of all of the Harry Potter films for home media at the very end of 2011. So once it’s sold out, it’s sold out.

There’s a silver lining for anyone who doesn’t complete their collection in time, though, because we’re also expected to be treated to a kind of ultimate edition (more ultimate than the complete 8-film collection that currently exists) sometime in the future, expected to come either at the end of this year or the start of next year. For now, here are the great new concept images to enjoy, letting us see what could have been. As usual, you can click to enlarge.

And if you’re missing your annual fix of Daniel Radcliffe, his first film following Harry Potter, The Woman in Black, is released on 10th February, and you can read our review of the film here.
