I went to 2 hmv stores in Manchester today and could only find Sleepless in each - the bigger store on Market Street was well stocked (about 8-9 copies) and they were in the horror section (pic is hmv1).
The second store was in the arndale (the old zavvi shop) and there was only 1 copy, which was hidde behind a load of other titles, again in the horror section (it's on the bottom middle row of the pic named hmv2)
Must admit, I never thought of looking in the World Cinema section
. I'll have a look when I'm next in...
There were no copies on any end-aisle displays or in the chart/new releases section.
Hope this helps!
