Everyone—and we mean everyone—is doing the ALS Ice Bucket Challenge. In case you've been living under a rock or boycotting Facebook, a friend challenges you to either donate $100 to ALS research or dump a bucket of ice water on your head. Celebrities have been challenging each other all week, from former president George W. Bush to Vogue editor-in-chief Anna Wintour to Taylor Swift.

Director Zack Snyder apparently challenged Malin Akerman and Carla Gugino​, who starred together in the Watchmen. They responded by making out. Their "steamy" session is quickly ruined with, of course, a bucket of ice water. Akerman in turn challenged Dan Stevens (Downton Abbey), Bradley Whitford and Nicol Paone​, both of which she co-starred with on Trophy Wife. Gugino nominated Danny DevitoJuliette Lewis and her manager, Jason Weinberg.

So, will anyone top that? Benedict Cumberbatch already did it naked.
