The Big Bang Theory Cast: Where Are They Now?
11. Laurie Metcalf - Mary Cooper
Laurie Metcalf's portrayal of Mary Cooper was one of TBBT's greatest performances in the show's history.
She played the character to perfection, which can sometimes be a daunting task when you don't see a character too often. We only actually saw Sheldon's mother 14 times throughout the 12 years the show was on air. Like with Laura Spencer's portrayal of Emily, it's a shame we didn't get to see more of her.
Metcalf rounded off her time on Roseanne the same year as her TBBT tenure came to an end, where she played three different characters throughout her over 200 appearances - Gilligan, Marsha Clark, and Jackie Harris, the last of the three characters she performed as. Since then, she's only actually appeared in two productions, but both of those have been quite high profile.
Laurie returned to her role of Jackie Harris on The Conners, the first of many TBBT cast members to appear on the Roseanne sequel comedy series, while also providing her voice to Toy Story 4 as the woman behind Andy's mother, as she also did in the second and third films in the franchise.
