The Kidd here...
If you've got any of the Marvel Movie Universe films on Blu-ray, this is going to be a bit of a tougher sell for you, considering the cost (you're looking at 153 bucks right now through Amazon pre-sale), but for a chance to own THE AVENGERS, the two IRON MAN films, CAPTAIN AMERICA, THE INCREDIBLE HULK and THOR, in addition to an extra disc of bonus material, some reproduced files, all in Nick Fury's briefcase with a glowing Tesseract you can call your very own, it might be worth it. Hell, I want one.

That's what you get if you pick up the MARVEL CINEMATIC UNIVERSE: PHASE ONE - AVENGERS ASSEMBLED Blu-ray box set on September 25, instead of just MARVEL'S THE AVENGERS by itself.
That bonus disc is secretive right now as far as its content, but I'm getting the feeling that only this box set will contain it, meaning for Marvel completionists, you're going to have to make some tough choices.
If you don't own a majority of this set though already for some reason, this is easily a must-get.
UPDATE: While you're at it, take a look at the individual disc sleeve designs created by Matthew Ferguson particularly for this box set (via Marvel). This thing keeps looking nicer and nicer.
