Brian George as Dr. V.M. Koothrappali
Raj’s hilarious father, the highly-regarded gynaecologist Dr V.M. Koothrappali, was played by Brian George. Dr. Koothrappali was usually seen over video chat because Raj’s parents lived and worked in New Delhi. The Israeli-English actor is also known for his performance as Babu Bhatt on Seinfeld.
Carol Ann Susi As Debbie Wolowitz
Debbie Wolowitz was an important part of the show’s history, despite the fact that she was never seen onscreen during its run. Carol Ann Susi, who was 62 at the time of her death, was diagnosed with lung cancer in 2014. In Susi’s honor, the character passed away as well, and the actors worked hard to convey their sorrow over the very real loss they were experiencing.
