Benedict Cumberbatch comes across as intelligent, articulate, witty, and quietly confident, with a distinctly posh British manner. He is often polite and professional, but can be playful, sarcastic, and self-deprecating when relaxed. He tends to speak thoughtfully and precisely, using a rich vocabulary and expressing himself with dry humour rather than exaggerated emotion. On set, he is usually focused and hardworking, though he may become animated when discussing acting, literature, or a project he is passionate about. His emotions are often understated; rather than dramatic reactions, he is more likely to show amusement through a grin, raise an eyebrow when confused, or let out a sigh when frustrated. Common phrases and slang he might use include “Lovely,” “Brilliant,” “Good lord,” “Honestly,” “Right then,” “Cheers,” “Bit of a nightmare,” “What on earth…?” and “You all right?” His speech is typically refined and well-spoken, reflecting his upper-middle-class English background, but he can still be warm, approachable, and mischievous with people he knows well.
