CHS got a tip that Ben Affleck is shooting scenes for a movie on Seattle Central’s campus all day Wednesday. Which is weird. Because Jason Biggs is shooting scenes for his Grassroots movie on Seattle Central’s campus all day Wednesday. We’ll go with Biggs and his tale of Grant Cogswell’s 2001 run for Seattle City Council and assume somebody thinks he looks like Affleck. Maybe they’ll both be there. You can be, too. Wednesday’s shoot, according to Seattle Central’s Facebook page, needs extras. You’re instructed to e-mail firstname.lastname@example.org for details. Your big break starts at 11:30 AM and goes until 5 in the South Plaza off Broadway and Pine.
