* The final battle at the top of the Windmill.
* Henry succeeding in giving life to the monster. His ecstatic shouting of "IT'S ALIVE!" and claim of "Now I know what it feels like to ''be'' God!" says it all.
* Crossing over into the real world, Boris Karloff's make-up was like nothing ever seen in cinema up to this point and remains the gold standard for non-mask monster make-up nearly 90 years later. The totally silent close-up of the monster's face when seen for the first time remains chilling.
