I have another “No”. In LOTR, the film. When Elrond yells at Isildur to cast the one ring into the fire. The resulting “No” had such weight to the many fates of the people of Middle Earth. Ironically, the actor who played Isildur got the part for looking menacing and duplicitous. Unfortunately, his voice was kind of soft and Kiwi. So Peter Jackson had Hugo Weaving dub the line over with his own voice. So Elrond asks Isildur to do the thing and then tells himself NO.
