THEN AND NOW: The cast of 'She's All That' 20 years later

"She's All That" was released in theaters in January 1999 and became an instant classic teen rom-com.

The film, which was loosely based on the George Bernard Shaw's play titled "Pygmalion" and the 1964 movie "My Fair Lady," focused on a high school student named Zack, who made a bet with his friend that he could transform any girl at William Henry Harrison High School into a prom queen. 

The cast of "She's All That" was comprised plenty of actors who went on to become notable names in Hollywood, including Rachael Leigh Cook, Freddie Prinze Jr., and Paul Walker.

Here's what the stars have been up to since the movie came out on January 29, 1999.

Rachael Leigh Cook starred as Laney Boggs, a clumsy student who was passionate about art.

She wasn't concerned with being a popular student at school.

Cook has since starred in even more movies and TV shows.

She guest-starred on "Dawson's Creek" in 1999, and starred as Clara in the 2005 miniseries "Into the West." Cook's other TV credits include parts on "Psych," "Perception," and "Robot Chicken."

Cook also had a cameo in singer Khalid's music video for "Young Dumb & Broke."

The 39-year old married "The Originals" star Daniel Gillies in 2004 and the couple has two children together, a daughter named Charlotte and a son, Theodore.  

Freddie Prinze Jr. starred as the school's jock and class president, Zack Siler.

He had the fourth-highest GPA in his class and was determined to turn Laney into a prom queen within six weeks because he couldn't stand the idea of losing a bet.
