I received the Fox "Horror" box today.
Three films -- "The Undying Monster", "The Lodger" and "Hangover Square."
I watched "Hangover Square" because I've seen it once before, on TV, back in the 1960s.  It fascinated me then, and it's no less fascinating now.
I feared the worst for this film's viability for home video since, to my knowledge, this DVD is its first home video release.  
It actually looks quite good.  I don't know if it's best-available print or the result of major restoration, but it looks pretty darned good.  Images are sharp, the b/w contrasts are excellent.  And the acting/production design/and most especially the stunning music score are SUBLIME!
And Linda Darnell makes you root for what happens to her!
