“Bring on the bucket,” says Cumberbatch as the cold water is poured over him. But, it turns out, this is the first of many.

Well, he was late. He didn’t do it 24 hours after Tom Hiddleston nominated him. Giving other celebs time to also nominate him.

So he ends up having to do it several times. Naked in the shower, in a white shirt, on a motorbike…

Yes, this is a lot of Benedict Cumberbatch getting drenched.

Cumberbatch’s ice bucket challenge is all in aid of helping to raise awareness and money in support of ALS also known as Lou Gehrig's disease and Motor Neurone Disease, a condition that attacks the spinal cord.

In the spirit of the social media craze, Cumberbatch has nominated Kylie Minogue, Lewis Hamilton and Harvey Weinstein.
