The epitome of uber-cool in shades and a brilliant white t-shirt, Idris Elba has revealed he was perfectly cast for his latest film, the survival adventure Beast. His character is tested to the limit by a giant marauding lion – but, personally, Elba always plays it cool in a crisis.Talking about the dangers facing his character – including the much-publicised scene where he punches the lion – Elba admitted “I’m really not the kind of personality who panics in a crisis. I’ve been in situations where, if you panic, you just make the wrong decision.Beast is in UK cinemas from Friday, 26 August.
