Get to know both the movies referenced -- as well as the individual TWICE members -- more in this breakdown of the key film moments. After you get done with your umpteenth viewing of "What Is Love?" and reading through this article, the only question you'll have next is: which movie to binge-watch first?
1. The Princess Diaries starring Nayeon (0:15)
The first movie reference comes via beloved Disney flick The Princess Diaries that gave Anne Hathaway her breakthrough role in 2001. Nayeon initially portrays Hathaway's awkward, nerdy character -- complete with big glasses and frizzy hair -- before later transforming into princess mode with slick hair and perfect makeup. Look out for TWICE members Sana, Mina and Jihyo initially playing the mean girls characters, one of which was played by Mandy Moore in the film.
Bonus: The Princess Diaries' original author Meg Cabot gave her co-sign to Nayeon and the girls on Twitter.
2. Ghost starring Jeongyeon (0:28)
TWICE vocalist Jeongyeon had the uneasy feat of recreating one of the most iconic film scenes from the '90s. Portraying Demi Moore's character in the blockbuster hit Ghost, Jeongyeon not only nailed the character's recognizable hairstyle but the same aura that made the role so lovable to parody the film's well-known pottery scene. With member Sana also popping up here to play Patrick Swayze's character, this moment will go down as yet another great (and adorable) parody of the Academy Award–winning movie's most famous scene.
3. La Boum starring Mina (0:40)
Internationally beloved French film La Boum is also featured in "What Is Love?" with the story of a young girl finding her way through a new school embodied by Mina. The singer plays through one of the movie's classic scenes when a potential paramour puts headphones on main character Vic and transforms her party experience.
4. Pulp Fiction starring Sana (0:50)
TWICE show their love to Quentin Tarantino with a spot-on take of Uma Thurman and John Travolta's classic dance from his 1994 hit Pulp Fiction. We once again get to see the TWICE members play opposite one another as youngest member Tzuyu takes on Travolta's role with the two ladies looking super-serious while busting out their best disco moves.
5. Romeo + Juliet starring Tzuyu (1:00)
Just after showcasing a more masculine image, youngest member Tzuyu gets super-feminine as Juliet for her spin on Shakespeare's classic love story. While there are a slew of references to pick from, TWICE looks to be paying homage to the Baz Luhrmann–directed Romeo + Juliet from 1996 -- that marked major career moments for both Leonardo DiCarprio and Claire Danes in the titular roles -- as Tzuyu wears an angelic look that had Romeo (originally played by a young DiCaprio, now played by member Jeongyeon) fall head over heels for his Juliet.
6. Love Letter starring Jihyo (1:12)
As a group made up of international members themselves, it only makes sense to see more countries represented in their movie references with TWICE's leader Jihyo acting in a recreation of 1995 Japanese film Love Letter. From the fashion styling to the acting, Jihyo nailed the blockbuster flick, that holds special significance in South Korea as one of the first Japanese movies played in the country after World War II.
7. La La Land starring Momo (1:22)
The most recent inspiration comes via La La Land, 2016's Academy Award–winning musical that scored Emma Stone the Best Actress Oscar. TWICE's main dancer Momo dances on Stone's role, donning the actress' iconic yellow dress, as Tzuyu embodies Ryan Gossling's beloved jazz pianist character. If any of the girl group's young fans didn't catch the previous movie references in the film, they undoubtedly would recognize this near-perfect recreation.
8. Léon: The Professional starring Chaeyoung (and Dahyun) (2:22)
The final movie moment comes via English-language, French production Léon: The Professional. TWICE rapper Chaeyoung plays Natalie Portman's spunky teenage character Mathilde as Dahyun plays the film's titular hitman Léon as perhaps the most-committed male character in the music with the hilarious 19-year-old donning fake facial hair.
