Continuing my Karloff at Columbia set from Eureka. The concept is more of the same when compared to The Man They Could Not Hang but I quite like it and it's understandable since it's written by the same guy (Karl Brown). It's still a very fun sci-fi thriller that delivers what you'd expect and is hugely benefited by having Boris Karloff in it. It has the silliness but also is tense and engaging, and the suspense is surprisingly effective in the third act. It is fast-paced and makes for a nice entertainment. Karloff once again shows his range and nails his character incredibly well. Always great to see this man in action. 3rd film from Eureka 'Boris Karloff at Columbia' set.
