What are some of the best examples of moments of realization in movie history?

For me it's "The Lovely Bones", when Mark Wahlberg sees the flower in his hand while talking to his daughter's murderer. His facial expression gave me goosebumps.What other scene out there will cause the same feeling? I don't mind getting spoilered, because the goosebumps happen even if I know about it :) via /r/movies https://ift.tt/MsXJUrd
