Kirsten Vangsness (Penelope Garcia)
Without a doubt, Kirsten Vangsness is one of the biggest stars of the show. After all, she is the only cast member to appear in both Criminal Minds and the spinoffs. She is best known for playing Penelope Garcia, the vegan feminist technical analyst on the team. It might come as a surprise that her career has slowed down. Her only movie credit since then is for a short film called Curtains.
Lola Glaudini (Elle Greenway)
After the second season of the show, Lola Glaudini left the project. Despite this, she made an impression during her short time on Criminal Minds. Elle Greenway, her character, was assaulted by a suspect, went through a breakdown, and shot a perp to death. The last incident caused her to leave the force. The actress has appeared on many other TV shows after she left the set.
