Aarti Mann as Priya Koothrappali
Aarti Mann was a familiar face in seasons four and five of The Big Bang Theory when she played the recurring character of Priya, Raj’s sister and Leonard’s occasional love interest.
Even though Aarti Mann had been acting long before her appearance on the show, it was her role as Priya that really got her noticed. This led to roles in popular shows like Suits and Grey’s Anatomy. Since then, she likely hasn’t had any trouble paying her mortgage and other bills.
Steven Yeun as Sebastian
Before Steven Yeun became a household name as the beloved Glenn in The Walking Dead, his first TV role was actually a guest appearance on The Big Bang Theory. He played the role of Sheldon’s former roommate, Sebastian.
There’s no doubt his career has skyrocketed since then. Even after his character was killed off in The Walking Dead, the projects have kept rolling in for this talented actor. He has two new films: Sorry to Bother You with Armie Hammer, and the Korean drama film, Burning. Plus, he owns a restaurant in Los Angeles, so his bank account is certainly thriving.
