Pulling out the big guns! The Obama administration is taking student sexual assault very seriously—so seriously, in fact, that it has enlisted the help of top Hollywood stars for its new PSA.

In the one-minute clip titled "1 is 2 Many," Seth Meyers, Steve Carell, Daniel Craig, Benicio Del Toro, Dule Hill, Vice President Joe Biden, and President Barack Obama all speak out about the dangers of sexual assault. 

"It's happening at college campuses, at bars, at parties, even in high schools," Hill says. 

Adds Meyers: "It's called sexual assault, and it has to stop."

The all-male group of A-listers and politicians implore fellow men across the country to stand up and protect their friends, sisters, wives, and mothers in the face of this unforgivable act. 

"It's up to all of us to put an end to sexual assault and that starts with you," Obama declares. Craig concludes: "Because one is too many."
