Wendy Simms, played by actress Liz Vassey, first appeared in the sixth season of “CSI.” Prior to this, Vassey was already a prolific TV star, appearing in the shows such as “All My Children,” “Star Trek: The Next Generation,” and “Beverly Hills, 90210.” Simms began a rivalry with David Hodges in her recurring role.
But she eventually grew to have feelings for him as they worked closely together in the lab. Following four seasons as a recurring character, she was ultimately promoted to star alongside the main cast. As many of the show’s actors renegotiated their contracts, Vassey permanently left the show following a season eleven episode.
Robert David Hall– Then
Robert David Hall took on the role of Dr. Robbins, who was the Chief Medical Examiner. Dr. Al Robbins did not have his first appearance until a few episodes into season one, Robert David Hall had the distinction of appearing in most cases in the CSI franchise.
Tragically, Hall lost his legs in a car accident in 1978, but this did not at all hinder his performance as Dr. Robbins. The injury was written into the role of Dr. Robbins, who is seen in a wheelchair in almost every scene, except for a few scenes in which he wears prosthetics.
Robert David Hall – Now
Although both of his legs were amputated in 1978, Robert David Hall never ceased acting. Many of his characters share his disability, including Dr. Robbins. Outside of acting, Hall is also a talented musician; he plays guitar, piano, percussion, and mandolin. He worked as a DJ for years in Los Angeles and has also recorded voiceovers for other projects.
Though he had a brief break in his career, the end of "CSI" has not ended his acting legacy. The seasoned performer has continued to grow his career, having appeared in movies such as "Rock Story" and "Aaah! Roach!" He also appeared as himself in the documentary "Diffability Hollywood."
Liz Vassey – Now
Liz Vassey made small appearances on quite a few television shows in the 90s and early 2000s before finding a stable platform for her career on "CSI." She appeared in 40 episodes of the 1995 show "Brotherly Love" with Andrew, Matthew, and Joey Lawrence.
Since leaving "CSI," Vassey also appeared on "Two and a Half Men," in addition to the TV show, "Necessary Roughness," and in 2019, "The Tick." And then, in 2023, she appeared in two episodes of the family drama series "A Million Little Things." Vassey has been happily married to David Emmerichs since 2004 and the couple is still going strong until this very day.
Jon Wellner – Then
Jon Wellner's journey on "CSI" began with a cameo appearance as a zookeeper in the show's fifth season. However, he patiently bided his time until his opportunity to become a part of the main cast arose in season thirteen. As Henry Andrews, the skilled toxicology expert, his role didn't demand a constant on-set presence.
Henry's character was portrayed as somewhat uptight, often fumbling with humor, yet his endearing nature shone through, making him a beloved addition to the ensemble. Despite facing challenges with comedic timing, Wellner's portrayal of Henry brought a unique charm and an engaging dynamic to the cast, further enriching the show's captivating narrative.
