Judging from the first batch of reviews, (see what I did there?) I think he's pulled off turning himself into a war machine quite well. So very proud of him!!!!!

Having Spielberg and Jackson already on his CV shouldn't hurt his chances. Cumberbatch is keen to diversify and prove that he can do far more on screen than the rent-a-toff roles his aristocratic bearing and Harrow-educated vowels might suggest. And, as his kite-surfing holiday hints at, he's not afraid of physical adventure. "I'd love to transform my body into some ridiculous war machine," he says, with a twinkle. Don't bet against this cerebral character actor reinventing himself as an action hero, given half the chance. "I want to have my Daniel Craig moment!" he laughs. "I want to run round a desert shooting guns at aliens and looking like I barely have to take a breath. I'd love to do all that shit!"
