CHICAGO — Get ready for some white knuckling excitement in the new Idris Elba action movie “Beast.”  

In the movie, Elba plays a recently widowed doctor and husband who brings his two young daughters back to the South African hometown village of his late-wife where they once lived, but an out of control lion is taking out humans.

Even with a simple script, it’s an effective, no-nonsense thriller and a master class in flawlessly incorporating computer generated scenes with the beauty and danger of South Africa.   

It’s a Dean’s List B+.
