Warner Bros. has just released the Harry Potter Complete 8-Film Collection in 4K in the UK.
This is a great-looking set with all films included. The real beauty is that all titles have remastered audio with DTS-X tracks.
Amazon UK is currently charging £79.99 that translates to about $88 compared to the US version coming in at $149.99.
However, be aware that the UK version includes 4K discs only. The US versions also come with Blu-ray discs, if that is worth an extra $60. No extras are included on these 4K discs, except for digital copy.
