Jennifer Aniston and Will Ferrell Get Serious

Will Ferrell and Jennifer Aniston are two of the stars joining the fight to end human-rights violations in Burma

Will Ferrell may be a big jokester, but his latest endeavor is no laughing matter. The Semi-Pro star is one of many celebs (along with Jennifer Aniston) who are participating in public service announcements to help end human-rights violations in Burma and free imprisoned Nobel Peace Prize winner Aung San Suu Kyi.

I can exclusively tell you that Ferrell’s PSA will debut online tomorrow at BurmaItCantWait.org as a kickoff for the Human Rights Action Center and U.S. Campaign for Burma’s new celebrity PSA program.

"Every now and again, a single person or event captures the imagination and inspiration of the world,” Ferrell says in his spot. “This moment belongs to Burma and to Aung San Suu Kyi. Please, honor her courage, honor your compassion and let this be the month you join an effort to change the world."

Aniston’s PSA will post online on Friday, followed by spots from other boldfaced names like Ellen Page, Anjelica Huston, Judd Apatow, Sarah Silverman and Sylvester Stallone.
