On the “007-The Daniel Craig Collection” Blu Ray/UHD Combo-Disc Set, the extended international cut of Casino Royale (2006) can be found only on the UHD Blu Ray, in the USA and abroad. This is confirmed by this review on The Digital Bits. The extended cut, which has 17 seconds of extra footage, was previously released on Blu Ray but was not available in the USA.
Is the BD the deluxe version or the first release?
