I guess によって that time they couldn't afford Clooney anymore, haha!
But still they could have mentioned Doug and Carol after the funeral, so we'd know they were there. That way they didn't need to hire the actors again.
Well it did kind of get me angry but then George sed in an interview, that they did ask him to come back for Mark's funeral but Geroge thought that his return might have overshadowed Anthony's (Mark's) funeral and he didnt want that to happen cause Mark was a much loved character
