Actor Benedict Cumberbatch—of Doctor Strange and The Power of the Dog—revealed to Marc Maron on WTF that he contracted COVID recently. He gave up caffeine and other stimulants to repair his body. "I got COVID and I just kind of cut out anything because I had it about a month ago, three weeks ago is when my sort of isolation ended," he said, adding he was vaccinated. "Double vaccines. We still got breakthrough case. Although I have to say the breakthrough thing, I think, vaccines do probably work for six months and then you should really look at it." He said he had "five days of really nasty fever" and lost his sense of "taste and smell, only just now coming back properly. I would get the taste of something and then it would just go like a ghost. It was like, oh, what was that? And then when it came back, it was the same thing. It was like, hang on, hang on. I think that's an apple. I know it is. Cause I'm eating one, but it didn't last."
