An unauthorized remake of Amphibian Man (1962)?

Rating: 5/10 (10 February 2018)

I have yet to actually see this, but has anyone yet realized this may very likely be an unauthorized remake of Amphibian Man (1962), a Russian film? The more I read about DelToro's movie, the more I see the similarities between it and the earlier Russian film no one seems to realize this movie is a LOT like.
