Both Matthew Macfadyen and Keeley Hawes attended the Lucy Liu exhibition and book launch event, named "Seventy Two" held on 21 September, 2011. You can view more information about the exhibition at Salon Vert or the Seventy Two Facebook page.
Matthew is sporting a beard, probably for his role as Oblonsky in the upcoming Anna Karenina.
Keeley may be showing off her Upstairs, Downstairs hairstyle, as well.
