Roddy McDowall plays the professor Sorenson who juices up a baboon with brain serum so he’ll be calmer,unfortunately he makes a mistake and instead of injecting the right serum,he injects the serum that turns him into a bloodthirsty predator.”Shakma” is a much better film than Tom Logan’s awful slasher “The Night Brings Charlie”.It’s full of violent animal action,mostly the baboon attacking and killing medical scientists and the other animals in the lab.”Shakma” offers a nice amount of blood and gore and the killings are pretty brutal.The acting is solid,the score is amazing and the baboon is downright aggressive.Overall this is an immensely enjoyable animal-on-the-loose horror flick that should satisfy genre enthusiasts
