Famous Actors Who Appeared On 'Grey's Anatomy' - The Delite

Famous Actors You Forgot Appeared On ‘Grey’s Anatomy’

As one of the longest-running medical dramas in history, “Grey’s Anatomy” has had plenty of opportunities for guest stars. During its lengthy run, the show — now in season 15 — has featured a ton of notable names, from Demi Lovato to Kyle Chandler.

Here’s a look back at some the famous actors you probably forgot once appeared on “Grey’s Anatomy.”

Elisabeth Moss

Way back in season three, Elisabeth Moss played Nina Rogerson, an overprotective daughter of a Seattle Grey’s patient. Her mother suffered from a condition that caused bones to grow at the site of any trauma. Sadly, her mom died while undergoing a risky surgery at the hospital.

Demi Lovato

The singer and actress played psych patient Hayley May in a season six episode. Hayley was incorrectly diagnosed with paranoid schizophrenia, despite her insistence that her condition wasn’t mental health-related. Alex eventually helped her uncover her real diagnosis, and she underwent surgery that allowed her to function normally.

Sarah Paulson

The “American Horror Story” star played a younger version of Meredith’s mother, Dr. Ellis Grey. She made her appearance during the season six flashback episode, “The Time Warp.” The episode revealed more details about Ellis’ relationship with Dr. Richard Webber.

Kyle Chandler

In season two, the former “Friday Nights Lights” star appeared as Dylan Young, a leader of the Seattle Police Department Bomb Squad. Sadly, his character died while attempting to carry a bomb out of the hospital. He later reappeared in season three as a vision to Meredith, after she fell into Elliott Bay and entered an afterlife-like dimension.

Mandy Moore

Mandy Moore’s first appearance as patient Mary Portman took place during one of the show’s most dramatic moments: the shooting at Seattle Grace Mercy West captured in season six. She and Dr. Bailey were locked in a room together during the emergency and tried to save Charles Percy after he was shot. Portman returned in season seven to undergo a surgical procedure but passed away after slipping into a coma.
