David Yates: That was the day they almost got hypothermia.  And fortunately survived.  It was also Emma’s birthday.  I said, “Happy Birthday Emma, we’re now going to give you hypothermia.”  It was tough for them and poor old Rupert was freezing.  And Emma, true to form, what I love about Emma is I said, “Are you guys okay?  Emma, are you okay?”  And she looked at me and said, “Don’t worry about me.  Look at these guys.  They’re dying over here.”  And she insisted they get in the warmth first.
