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.
Wallace Langham – Then
Lab technician David Hodges, played by Wallace Langham, joined the team in season three, spending five seasons as a recurring character before he was promoted to the main cast in season eight. As a germophobic over-explainer, the character of Hodges was not exceptionally charming.
Langham described his character as a "pain in the (butt)" and a suck-up, but the role added narrative texture to the cast as a whole. Langham started off in the acting world in small roles in a bunch of '80s movies. Funnily enough, he used to be credited in acting roles as "Wally Ward." He has come very far since.
Wallace Langham – Now
Wallace Langham began his acting career in the mid-80s, with roles peppered through numerous tv shows in the nineties. From the earliest part of his career, he is probably most well-known for his role as Mark Ratner on the "Fast Times" TV series. Since CSI ended, Langham has successfully sustained his career, maintaining the same pattern of work till now.
He has appeared on "Grey's Anatomy," "Veronica Mars," and can also be seen in the new short film, "The Ball Method." In 2023, Langham had a recurring role as Melville Phipps in what turned out to be the final season of HBO's "Perry Mason."
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 – Then
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.
