You know Andrew Lincoln as the group's fearless leader, Rick Grimes.
He's one of the (now) five original cast members still kicking, along with Carl, Carol, Daryl and Morgan.
Before he took on the lead role in TWD, he worked on the popular UK show "This Life," but his most notable role was Mark from "Love Actually."
It's hard to picture Norman Reedus playing anyone but Daryl Dixon. But before he became the fan favorite he starred in a pretty popular movie.
You might recognize him from his leading role in 1999's "The Boondock Saints" where he acted alongside Sean Patrick Flanery and William Dafoe as the priest-avenging Murphy MacManus.
He also played Judas in Lady Gaga's 2011 music video "Judas."
Danai Gurira, who plays Michonne, proved her prowess on TWD and has since been cast in Marvel Studio's "Black Panther."
Before her big break as the samurai slayer she had parts in "Ghost Town," "Law & Order," and HBO's "Treme."
Melissa McBride has taken the role of Carol further than anyone could have expected.
She helped Carol dodge a bullet when the directors decided to kill off T-Dog, diverting from their original plan to say goodbye to Carol.
McBride showed off curly locks in season one of "Dawson's Creek." She played Nina who Dawson approached at a bar.
McBride also had parts in Stephen King's 2007 hit "The Mist" and "Pirates of Silicon Valley."
Her role in "The Mist" might have been minor, but she made a major imapct in the film's infamous ending. Plus, she shared the credits with her future co-stars Jeffrey DeMunn, a.k.a. Dale, and Laurie Holden, who played Andrea.
Maggie Green has had one of the roughest plot lines on the show. She lost her entire family and in the most recent season, her husband too.
Lauren Cohan's past roles weren't as somber. She acted alongside Ian Somerhalder as a love interest for his character, Damon Salvatore, on "The Vampire Diaries."
She also played Vivian Volkoff in the short-lived series "Chuck."
Television fans probably recognize this heartthrob as Denny from "Grey's Anatomy." He was Katherine Heigl's love interest and an early series regular.
You may also recognize Morgan from his role as the Comedian in 2009's "Watchmen" adaptation.
Her love life and hardcore attitude has made her a favorite on "TWD," which is a complete 180 from the shy, nerdy Angela she portrayed in "Twilight."
Austin Nichols played one of Rosita's love interests until 2016's mid-season finale when he proved he just doesn't have the guts to make it in the apocalypse.
Thanks to Negan, Nichols didn't last too long, but on "One Tree Hill" he was in a whopping 73 episodes playing Julian Baker, who married Sophia Bush's character, Brooke Davis.
The on-screen romance carried over for Nichols and Bush who dated for six years before ending things in 2012.
