There are two listings on Amazon.
Australian- Description states region A/B/C. Customer review states it's region coded and won't play in U.S.
UK(Movie Time Banner on cover)-description states region B/2. Further down the page "all region pressing" is mentioned. DVD Talk review says all region and has this cover as the amazon link to order.
Don't have all region player and looking for positive confirmation which to get.

I barely understood what you said.

Sounds like the DVD Talk version is the way to go.

The thread title is accurate then.

Isn't Shout suppose to release this later this year?

Yes. There's a new UK version coming out on August 4th, but no announcement yet from Shout! for their Region A release.

If I were the OP, I'd just wait for the new version.

The old UK edition is Region Free and looks pretty damn good. A sizable step up from the recent Lionsgate DVD.
Shout announced it had the movie and would be releasing it last year...but still nothing. It should have been announced by now. Don't understand what the hold up is.

Thanks for replies. I'll hold out awhile to see what happens with Shout. At least I know which is all region now.
