Henry Cavill and Amy Adams complete the Ice Bucket Challenge
Amy, 40, can be seen introducing the clip, sat alongside Henry, 31, who is dressed in his iconic Superman outfit.
After a short speech, in which the actress nominates her siblings, the co-stars are ready to go. And while Amy is drenched with icy water from just one bucket, Henry puts in a superhero effort and is soaked by six in total.
Barely flinching as he is covered in freezing water, the handsome star looks up at the camera at the end of the challenge, and says with a smile, "I'm so cold!".
Henry and Amy join a number of stars who have recently taken part in the ALS challenge, including Leonardo DiCaprio, Courteney Cox, Kate Moss and Benedict Cumberbatch.
