Yup, me too - all credit to Royal Mail / Zavvi for the next day delivery

I suppose if packages from HMV can be next day then why not from Zavvi . . .
Extremely elegant steelbook (unlike clunky previous) and like almost everything about it . . .
- The best part being the semi-circular metallic sheen under the craft representing the light emitting from it created by the selective removal of the white base coat layer in that section and best seen when you tilt the steel slightly for the ambient light to hit it. An oil slick with its rainbow colours is possibly the best way to describe the effect as in "iridescent".
RE: Steelbook itself - deep, rich "Space" colouring reminiscent of other equally good "Space" steelbooks such as CLOSE ENCOUNTERS, GRAVITY or STARGATE.
RE: partial slip - as elegant as the steel itself in the same deep, rich blue colouring with just those two BBFC stamps to slightly spoil the effect.
RE: AUDIO: Info I'm picking up is that this is 5.1 and not the 7.1 listed on the slip . . . with the DTS-HD Master Audio 7.1 reserved for the upcoming 4K ULTRA HD edition.
A couple of changes I would have made - one tiny the other less so:-
1) Omitted the silver printed "TWENTIETH ANNIVERSARY EDITION" on the front or printed it in a different colour so that it doesn't stand out but that's so minor it's hardly worth mentioning.
2) De-bossed the "ID4" bit of the title even though it does have a very cool effect as it is and not single colour blocked.
All in all: an 8/10 steelbook.
