There's a slight problem with the "Superman II", "Superman III", "Superman IV" and "Superman Returns" BD entries.
Specifically, the details for the first disc in the UK's "5 Film Collection" set are incorrect for each one. The first disc in the "5 Film Collection" is exactly the same as the first disc in the larger "Anthology" set, i.e the theatrical edit with the exact same extras.
The entry for the original movie has already been corrected - I emailed that one in ages ago. Hadn't noticed the others at that point!
