In the wake of the horrifying cyclone that hit Myanmar, which is estimated to have killed between 100,000 and 200,000 people and displaced as many as 1.5 million more, celebrities have responded in different ways.

Ben Stiller, Téa Leoni, Nicole Richie and Joel Madden have recorded PSAs for UNICEF, while Not on Our Watch, the nonprofit cofounded by George Clooney, Brad Pitt, Don Cheadle, Matt Damon and others, has already pledged half a million dollars to Save the Children.

Even Sylvester Stallone used a Japanese press conference for the DVD release of the latest Rambo installment, which features the character battling it out in Myanmar, to speak out. "I think what's going to come out of this devastating cyclone—and the fact that our film has made it much more apparent of the violence that these people live under—I think there's going to be great social change in that country, because they can't hide anymore," said the actor, who also showed off his bow-hunting technique.
