88 Films have released Castle Freak on DVD
in the UK, and will also release it on Blu-ray
The UK DVD literally blows away the old R1 DVD, which looks like a VHS tape in comparison.
The UK DVD is 16x9 widescreen and looks to be sourced from the original negative prints, and is also fully uncut. It includes the videozone, the Castle Freak trailer (also 16x9 and from a film source), and 10 other FM trailers. It also has reversible artwork.

The forthcoming Blu-ray should look fantastic...
