As far as I can tell there are something like 6 BD releases pending for this film here in the U.K.:-
1) Steelbook - HMV Exclusive 3D/2D + UV - 1 (?) BD
2) Amaray - 3D + 2D + UV - 2 (?) BDs
3) Amaray - 4K ULTRA HD + BD + UV - 2 BDs
4) Amaray - BD + UV - 1 (?) BD
5) Amaray - Amazon Exclusive Limited Edition SUPERMAN STATUE "Collector's Edition" 3D/2D + UV - 2 (?) BDs
6) Amaray - Amazon Exclusive Limited Edition BATMAN STATUE "Collector's Edition" 3D/2D + UV - 2 (?) BDs
Confusing, as often is, with 2 BDs listed in one place and 1 BD in another for the same item - not sure if the 3D/2D is on the same disc - as listed at HMV and BR.com for the steelbook - or two discs as listed at Amazon for other 3D/2D editions . . .
Without the certifications it's not possible to confirm the items above contain anything other than the 12A Theatrical Release Cut or even confirm it's a case of "1 movie, 2 cuts" (whether there's a "15" Certificate Extended Cut included here or not).
HOWEVER, with 151 mins. listed here in the U.K. as the runtime and the same in The States - for all BD listings for this film at BR.com - the only difference between the two countries appears to be that the U.S. editions include "1 movie, 2 cuts" in the listings.
According to the BBFC "All known versions of this work passed uncut . . . Some versions of this film are displayed in the 3D or IMAX format and some younger children may find them a more intense experience"
Regarding the TBC artwork: This image is from a poster designed by WORKS ADV of Los Angeles and is one of thirteen they designed for this film and the only one of two with both characters together . . . looking at both posters I know which one I'd prefer on the front and it's not this one.
