The Maltese in Game of Thrones
There were the fun times too, of course. Both Neil and Steffi mentioned the part where Sean Bean is being dragged by guards through the crowd and the extras have to yell at him (giving more details would constitute a spoiler and those who haven't yet read the books would hate me forever).
"Most of us found it just weird to shout at this fantastically famous actor while he's being dragged literally inches away from our faces!"
