This Friday, the Leonardo DiCaprio-narrated and -produced green documentary The 11th Hour opens in theaters. I'd bet the filmmakers, sisters Nadia Conners and Leila Connors Petersen, were pretty stoked to get a big name to endorse their film and their cause since this seems to be a good way to raise awareness.
Angelina Jolie is, of course, a huge proponent of using her celebrity for good, as is Brad Pitt, most recently with his sustainable New Orleans houses. Pitt also has some impassioned Hollywood colleagues as George Clooney and Don Cheadle continue to help the ongoing crisis in Darfur.
But does this sort of thing work to get more people involved? Do you find yourself inspired to do good deeds based on the causes that celebrities get behind?
