Washington, Jan 16: American actor Will Smith, who is elated with Barack Obama being elected to the White House, has revealed that he believes that America''s first black president will "change the world forever".

Smith has been an ardent supporter of Obama and even appeared in a star-studded public service announcement advert to encourage people to go the polls, and was ecstatic when he elected in November last year.

"It''s not just revolutionary, it''s evolutionary. Never before in the history of the planet has someone, a group of people, moved from the slave class of empire to be elected to the top spot," Contactmusic quoted him as telling British morning show GMTV.

The `I Am Legend' star not only views the historic appointment as life changing, but also says that it is the one moment that he and his family, who was brought together by the occasion, will always remember.

"It''s just such a huge moment for America and for the world, it''s something I believed was real and possible for so long. I carried myself around the world in that way as if it could be true, possible, so there''s a deep truth in me that was validated on (Election Day) November 4th," he told the BBC.

"We watched it together as a family. With my kids it was no big deal, whereas for myself and for (wife) Jada, and even more so for our parents, who lived through the struggle for equality, it was so huge, but for our kids the world is different.

"(The world) has changed forever. The ideas and the fibres that are created for America have never been more true than today," he added. (ANI)
