Brittany Murphy, who played the "adorably clueless" Tai, passed away in 2009, but her memory still lives on with her co-stars. The entire cast agreed that it was Murphy's "contagious" laugh that was most memorable. "So, so genuinely sweet," Justin Walker, who played Christian in Clueless, said of his co-star. "For a week, I couldn't believe it was real."

Alicia Silverstone added sweetly, "I taught her sporadically."

Breckin Meyer played Tai's boyfriend Travis on the show and said of the on-screen couple's future, "Travis and Tai would still be together, and would create like an Instagram on accident."
