I purchased THE LION IN WINTER BD at FNAC in Madrid for 11 euros a few days ago.
There is no region specific indication on the back. I played it last night here in New York and it is All Region:-)
Although not "restored" it does look significantly better than the DVD version...so I am pleased that this is available on Blu. If you want to look for it on line it is "El Leon en Invierno".
