The Boston Comic Con announced earlier today that they have added Laurie Holden, who played Andrea on AMC's The Walking Dead, to their lineup of talent. Jon Bernthal, who had previously been scheduled to appear, had to pull out last week due to a conflict with his filming schedule.
Holden will appear alongside her co-star Lauren Cohan to sign autographs at the show, which takes place this weekend. Despite taking place just a few blocks from where explosions rocked the Boston Marathon on Monday, the convention organizers have decided to go forward with the show--although they've asked cosplayers to leave their weapons at home to help security minimize their increased workload.
In addition to The Walking Dead and a run on The X-Files, Holden is currently executive-producing the feature film Honeytrap, described as "an urban drama seen from a girl's point of view."
