He thinks his own name sounds like “a fart in a bath”.
“Cumberbatch - it sounds like a fart in a bath, doesn't it?” he jokes. “What a fluffy old name. I can never say it on a Monday morning. When I became an actor, Mum wasn't keen on me keeping it.”
Which is probably why, initially, he used his father's surname, Carlton, instead. “When I started, I just assumed I couldn't be called Benedict Cumberbatch,” he recalls. “But then, one day, I told someone in the business what I was really called and they said, 'That's great, that's something you can use to stand out.'”
He's been Cumberbatch ever since.
