The Law & Order: SVU Episode You Forgot Starred Carol Burnett

When it comes to casting celebrity guest roles, no one does it better than the hit NBC crime show "Law & Order: SVU." The show has had a slew of A-list celebrities join their cast for an episode or two, seemingly launching countless careers.

According to Wolf Entertainment, the list of guest stars is both so long and so impressive that you may have forgotten that some stars even appeared on the show. Some of the most notable actors to join the likes of Mariska Hargitay and Christopher Meloni are Alec Baldwin, Elizabeth Banks, Bradley Cooper, and Viola Davis, just to name a few.

Some of these guest stars appeared on the show before they even got their big break (via Entertainment Tonight Canada). Adam Driver, known best for his role in the latest "Star Wars" films, is just one of the guest stars who has turned heads on "Law & Order: SVU," playing a criminal on the show before he rose to fame. However, one of the show's best guest stars had been a big name for decades when she took on a role on "SVU."

Carol Burnett was far from funny in her "SVU" cameo

Carol Burnett had been a force in the entertainment industry before she stepped on the set of "Law & Order: SVU." She got her start in acting in New York City after a mysterious benefactor paid her way to live in the Big Apple (via Britannica). She instantly turned heads with her comedic skills and would climb up the ladder, all the while helping pave the way for women in comedy.

Best known for her variety show, "The Carol Burnett Show," Burnett was constantly making audiences laugh. However, when she appeared on "SVU," her character was far from the hilarious ones she portrayed on her own show.

Burnett's cameo on the show took place during Season 10 in an episode titled "Ballerina" (via PopSugar). Burnett wasn't making us laugh when she took on the role of Birdie, a black widow character who had killed her husband. The dark role was considered to be outside of Burnett's wheelhouse, but her acting skills are so good that she had us all convinced she was actually evil. At the end of the day, Burnett used "SVU" in 2009 to prove that her acting chops are well-rounded, that she can do it all.
