Sara Gilbert as Leslie Winkle
Is it a requirement that if you appeared on Roseanne, you have to appear on The Big Bang Theory? I mean, that’s what it’s looking like! Sara Gilbert has made many appearances on shows such as 24, Will & Grace, and Private Practice. Since 2010, she’s also been the co-host and executive producer of The Talk, a talk show. On TBBT, she was downgraded to a guest role as the producers just couldn’t come up with any new material for her character.
