Sitting side-by-side on the set of their upcoming film, Batman v Superman: Dawn of Justice, the pair remained in costume as they accepted their nominations during a short video posted on Vimeo.
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!".
