Classic Amicus. A little bit of camp but a lot of fun. The nightmare sequence was a delight. Also loved the various two-shots of an eyeless skull facing off against Peter Cushing, the greatest eye-actor in history. Mad respect for the multiple shots from the inside of the skull. Mad audacious.

(Minor aside: since this is firmly in the era of using asbestos for snowflakes in films, I couldn’t help but wonder what kind of toxic shit Cushing was breathing in during the gas sequence).
