BEAST has Idris Elba fighting off Lions.

Idris Elba stars in a pulse-pounding new thriller, BEAST. It is about a father and his two teenage daughters. They find themselves hunted by a massive rogue lion intent on proving that the savannah has but one apex predator. Elba plays Dr. Nate Daniels, a recently widowed husband. He returns to South Africa, where he first met his wife, on a long-planned trip with their daughters to a game reserve managed by Martin Battles (Sharlto Copley, Russian Doll series, Maleficent), an old family friend and wildlife biologist. But what begins as a journey of healing jolts into a fearsome fight for survival when a lion, a survivor of blood-thirsty poachers who now sees all humans as the enemy, begins stalking them.
Iyana Halley plays Daniels’ 18-year-old daughter, Meredith, and Leah Sava Jeffries plays his 13-year-old, Norah. BEAST is from visceral, experiential filmmaker Baltasar Kormákur. He is the Everest and Universal Pictures’ 2 Guns and Contraband director. BEAST will be in theaters on August 19th.
