Avengers: Age of Ultron doesn’t hit American theaters for another week, but Marvel’s latest superhero epic opens today in many theaters around the world. This means that you need to tread cautiously if you want to avoid spoilers, but it also means that Amazon.co.uk is already offering its users the chance to pre-order the film on Blu-ray and DVD. We know that the window between theatrical and home releases are shrinking, but that’s just ludicrous. However, it’s the details about the disc that should get fans stroking their chins and saying “Hmmm.”

As you can see in the announcement below, the disc version of the film will feature an “extended version” an an “alternate ending.” We would like to comment further on this, but we haven’t seen the film yet. So we have no idea what could be different. Yet.

We do know that director Joss Whedon’s original cut of the film ran over three hours, which is significantly longer than the final theatrical running time. It wouldn’t surprise us at all if the home release restores some of the darlings he was forced to kill on the road to delivering a non-bloated and watchable movie. He previously told Collider that he didn't know exactly how much, but that we'd get a “goodly sum” of additional footage on the DVD. We do know that the mysterious woman from the trailer was a scene that never made it into the movie, so perhaps she re-appears?

As for that alternate ending ... who knows? Whatever it is, it surely can’t be too different than the finished version. After all, the Marvel Cinematic Universe is all about continuity. You don’t want to muddy those waters, especially when the nerds will eat you alive for any inconsistencies.

Avengers: Age of Ultron is playing in many theaters around the world at this very moment. It opens in the U.S. on May 1.
