Damon voices footrace history

BOSTON - Matt Damon's ties to the Boston Marathon are so personal they're stained with sweat: He's never run it himself, but his father and brother have four times.

That makes the Academy Award winner and Boston native the perfect choice to narrate the first full-length documentary about the marathon, the filmmakers said on Monday.

Frank Marshall, the executive producer of Boston - which premieres in its namesake city on April 15, two days before the 121st running of America's most venerable marathon - called Damon "the ideal narrator".
