When Matt Damon and pal Ben Affleck were struggling actors, they lived in a modest apartment near Hollywood Boulevard. Damon said he used to look at the stars on the boulevard sidewalk and dreamed of seeing his name on one of them someday. So when it came time to receive one Wednesday, Damon reacted with disbelief.

"A few times in my life I've had these experiences that are just kind of too big to process and this looks like it's going to be one of those times," Damon said during a Hollywood Walk of Fame ceremony attended by his wife, mother and a throng of screaming fans.

The star of upcoming thriller "The Bourne Ultimatum," then gave a nod to his hometown baseball team.

"I'm thankful the Red Sox are in first place," said Damon, who grew up in the Boston area.

Damon, 36, won a screenwriting Oscar with Affleck in 1998 for "Good Will Hunting." He has also starred in "The Departed," "The Good Shepherd" and the "Ocean's Eleven" franchise. He stars as the amnesiac assassin Jason Bourne in "The Bourne Identity" and its two sequels.
