In for a penny, in for a pound. I've picked up all the Arrow Shawscope releases alongside these Shaw Brothers Classics, so I'll be picking this box set as well.
I am hoping for a Night of the Demons boxset at some point, possibly from 88 Films as I have their NotD 2 release and this suggests the license for all three is available in the UK.
The Shaw Brothers Classics is tricky as I am all in on Arrow's Shawscope releases and there is some crossover but it's only a few titles at the moment but Shawscope 3 must be in the works...
