Kelli Williams played an almost identical character on her earlier show, Lie to Me (2009). In that show, she played Dr. Gillian Foster, the assistant to Dr. Cal Lightman (Tim Roth), where she was an expert in identifying deception, via facial expressions and involuntary body language. In Found, her character, Margaret Reed, is the assistant to Gabi Mosley (Shanola Hampton), an expert in identifying deception, via facial expressions and involuntary body language.
Despite the character of Hugh "Sir" Evans being much older than Gabi, who was a teenager when she was kidnapped, Mark-Paul Gosselaar is 3 years older than Shanola Hampton.
This series marks the fifth consecutive time where Dutch and Indonesian-American actor Mark-Paul Gosselaar has headlined a show with a Black co-star. In addition to working alongside Shanola Hampton in "Found" (2023), Gosselaar worked with Tone Bell in "Truth Be Told" (2015), Kylie Bunbury in "Pitch" (2016), Saniyya Sidney in "The Passage" (2019), and Tika Sumpter in "Mixed-ish" (2019).
