Head on over to the beaver for a gander at the new IT! THE TERROR FROM OUTER SPACE blu ray from Olive Films. It streets next week and I'll provide a full review when I get my hands on a copy...

It's interesting that the reviewer points out the shadowy, obscured way that the alien monster is photographed as one of the film's weaknesses. That's exactly the opposite of how I feel. I think director Cahn shot a cool but ultimately absurd looking rubber suit in the best way possible. The stark, backlit, smokey images are forever burned and branded into my brain since my original multiple viewings on early 60s TV!
