I got this movie from the 100 pack at Wal Mart. once I found out who was in it I just had to jump right in,, James Best.. Sheriff Roscoe P. Coltrain. apparently on an island somewhere, overpopulation has become a real problem, and these Giant Killer Shrews are taking over the population and the island. just imagine yourself on an island like that where you are being over run by these huge gigantic shrews, I thought James Best did a wonderful job in this.. he was very funny, and his acting was also pretty good,, I guess back in the late 50's you could say that the undertone to this movie was a warning about overpopulation and what it will mean in the future if we as humans try to take over a certain land mass or area... very decent film from the 50's that isn't Oscar material, but not bad either,, I would recommend it even if I never heard of James Best.
