14 Actors You Totally Forgot Were on 'Supernatural'

Several famous (or about to be famous) faces have appeared on the long-running "Supernatural" as demons, vamps, witches, and victims -- but do you remember them?

Sarah Shahi, Season 1

The actress, who currently plays Sameen Shaw on "Person of Interest," was the mysterious (and deadly) Woman in White in the pilot episode. Shahi was also the star of the "Nancy Drew" reboot that was nixed by CBS for "skewing too female."

Cory Monteith, Season 1

The future "Glee" star was a camper who gets slaughtered by a Native American spirit known as a "Wendigo" in the episode of the same name.

Alden Ehrenreich, Season 1

The actor, who was recently cast as the young Han Solo, was only 15 when he played "Ben Collins" in the Season 1 episode "Wendigo," a teen looking for his lost brother. His older sister and Dean get captured by the deadly Wendigo, and Ben and Sam rush to their rescue.

Linda Blair, Season 2

The star of "The Exorcist" played a Baltimore cop in "The Usual Suspects," where Dean is in custody as the prime suspect in a bizarre double murder. She ends up turning to Sam to solve the case and, yes, a joke about pea soup is made.

Gary Cole, Season 2

When people begin dying on a horror movie set in the "Hollywood Babylon" episode, Sam and Dean drop in as production assistants to help solve the case. There, they encounter the "Office Space" and "Veep" star, a clueless producer who ends up being one of the ghost's victims.

Sterling K. Brown, Seasons 2 & 3

Gung-ho vampire hunter Gordon, who became a vampire himself, appeared in four episodes from 2006-2007. Brown went on to roles in "Army Wives" and "Person of Interest," but really broke out with his performance as Christopher Darden on FX's "American Crime Story: The People v. O.J. Simpson."

Aldis Hodge, Season 2

The actor, who starred as MC Ren in "Straight Outta Compton," played Jake Talley, one of the "Special Children," including Sam, who are abducted and forced to battle to the death in the two-part 2007 episode "All Hell Breaks Loose." Hodge also has a recurring role on "Turn: Washington's Spies."

Ashley Benson, Season 4

Two years before landing a lead role on "Pretty Little Liars," Benson played a cheerleader who's really a centuries-old witch in "It's the Great Pumpkin, Sam." She summons the demon Samhain, who promptly kills her.

Candice King, Season 4

The "Vampire Diaries" star (billed here as "Candice Accola") was the rare guest star who wasn't a vampire, ghost, or demon. She appeared in "After School Special" as a girl Dean once dated in high school.

Bellamy Young, Season 5

The "Scandal" First Lady appeared in "Sympathy for the Devil" as Sarah, one of the many vessels for Lucifer. Before she was murdered, she was married to Nick (Mark Pellegrino), who became the most familiar incarnation of Lucifer on the series.

Paris Hilton, Season 5

Fans were in an uproar when it was announced that the celebrity heiress was going to appear on the show. In the "Fallen Idols" episode, Hilton (along with Abraham Lincoln) is just one incarnation of the "Leshi," an ancient Eastern European forest god who relies on human sacrifice to survive.

Sarah Drew, Season 5

In "Swap Meat," the "Grey's Anatomy" star played a high school student whose friends dabble in the black arts: They summon a demon, who ends up possessing her. You've never seen Dr. Kepner rip out someone's heart and then lick the blood off her fingers!

Mike Farrell, Season 8

The "M*A*S*H" star appeared in the "Hunteri Heroici" episode as a psychic capable of altering reality with his visions, resulting in several people dying in a gruesomely cartoonish fashion.

Lesley Nicol, Season 10

Don't recognize this evil, cleaver-wielding witch from the episode "About a Boy?" (She turns adults, including Dean, into children so she can eat them.) She's better known for her turn as a much nicer cook, Mrs. Patmore on "Downton Abbey." What would Mr. Carson say?
