Can’t be 100% sure but it’s very, VERY likely that they are all going to be in spanish only, as only few spanish releases of old italian or spanish films have english options.
The good news is that at least Who Killed Johnny Ringo was of great quality, as good as the best MGM or KOCH Media releases. Anamorphic 2.35:1 widescreen, very sharp picture and great colours. Most spanish DVDs are just letterbox and look like as if they were taken from good quality VHS, so it was a pleasant surprise.
I added the missing english aka names to the list so it should be 100% complete now. Thanks, Hombre!
