Watch ‘Big Bang Theory’s’ Tribute to Carol Ann Susi (Exclusive Video)

"Here's to You, Carol Ann Susi" is among the special features on the season eight Blu-ray/DVD set.

The cast and creators of CBS' The Big Bang Theory have nothing but amazing things to say about late and great former co-star Carol Ann Susi.

In a special tribute video included on the season eight Blu-ray/DVD set, titled "Here's to You, Carol Ann Susi" and seen above exclusive to The Hollywood Reporter, creators Chuck Lorre, Bill Prady and showrunner Steve Molaro — as well as the cast — share their fond memories of the actress who voiced the late Mrs. Wolowitz.

"In the writing, we've painted a fairly horrendous picture of Mrs. Wolowitz, which was nothing like Carol Ann — at all," Molaro says.

Susi, who never appeared on-screen for her role, died in November after suffering from cancer. She was 62.

Following her passing, producers opted to write her passing into the show and during season eight's "The Comic Book Store Regeneration" episode, wrote out Mrs. Debbie Wolowitz when her son, Howard (Simon Helberg) learned that his mother had passed away in her sleep while on vacation in Florida.

"The first thing we talked about was how sad we were that our friend was no longer with us. It took a while for that devastation to calm down before we could even think about [Mrs. Wolowitz's fate]," Molaro told THRfollowing the February episode. "We couldn't bring ourselves to start to think about it. Eventually the needs of the show [forced the issue] and we had to come up with a plan, and I don't think we could bring ourselves to replace the actor. The thought of it felt awful to us. That left us with two options: We send the character away — which seemed false and fake — or we go right into it and write it into the show, so that's what we chose to do."
