Checking in! Many famous faces have visited Grey Sloan Memorial Hospital during its nearly two-decade run some of which fans may not remember. While multiple stars appeared on Grey’s Anatomy for long stretches, others had one-episode stints.
Demi Lovato was a very recognizable star when they landed a one-off part on an episode of season 6. Millie Bobby Brown, on the other hand, was relatively unknown when she appeared on the season 11 episode “I Feel the Earth Move.” One year after she appeared on Grey’s, the English actress started her stint as Eleven on Stranger Things.
Other actors had entire story arcs on the ABC drama. Jeffrey Dean Morgan, for example, crushed hearts as Denny beginning on season 2 of the medical drama, which aired in 2006. He ended up starring in 23 episodes as Izzy’s (Katherine Heigl) love interest. He recurred through season 3 and his last appearance was in season 5.
Four seasons later, his real-life wife, Hilarie Burton, appeared on the show in the role of Dr. Lauren Boswell. She even had a quick fling with Dr. Arizona Robbins (Jessica Capshaw) during her three-episode arc, which caused a stir for fans of Arizona and Dr. Callie Torres (Sara Ramírez).
