- Hilarious in Hindsight: Max Campion/Johnny Martin would later try to prevent Lemon's assassination in X-Men: Days of Future Past. And Penelope's father would go on to render mutations extinct in Logan.
- Hollywood Homely: Somehow, in this universe, all it takes is a pig nose to make Christina Ricci an unspeakable horror. Not exactly Cameron Diaz in Being John Malkovich for the viewer.
- Memetic Mutation: That .gif◊ of Peter Dinklage pressing his hand romantically to a prison glass window before Flipping the Bird when the other guy comes to touch it is from this movie.
- Moment of Awesome: After Max accidentally gets a photo of Penelope, he returns to Lemon and Edward. ...Only to smash the camera inside his suit, destroying any photographic evidence of the pig-faced girl. But he doesn't leave without telling them to leave her alone, that she's not the monster they think she is.
- Nightmare Fuel: Penelope, to everyone.
- Imagine wearing a carnival mask based on your own formerly deformed face, which is what Penelope does at the end.
- Older than You Think: The film is not merely a Gender Flip of "Beauty and the Beast", it is actually based on the once-popular Urban Legend of the pig-faced woman, almost word for word.
- Retroactive Recognition: In 2011, both James McAvoy and Peter Dinklage became widely recognized by the general public for portraying Charles Xavier and Tyrion Lannister, respectively.
- Tear Jerker: After Max turns down Penelope's proposal that he marry her, Penelope goes to her room whilst her mother insists she'll never give up trying to find Penelope a suitor who will love her. All the while, Penelope looks back on all the previous suitors who ran from her and jumped out the window. The sound of the glass breaking is notably audible. A second time watching it, it becomes clear it represents the sound of her breaking heart.
YMMV / Penelope
