Charlie Sheen – Himself
Well, Charlie Sheen is not the kind of guy that you need a long introduction for because we know him all too well. Charlie made a guest appearance in a 2008 episode titled “The Griffin Equivalency,” and it was a good one.
In 2017, the now 55-year-old appeared in the films 9/11 and the tv series The Goldbergs.
Regina King – Janine Davis
Janine Davis had a recurring role on The Big Bang Theory and was played by the legend Regina King. The veteran actress has so many accolades to her name, and we believe she needs to make more appearances and soon too.
King’s popularity came after she starred on the NBC series 227 as Brenda Jenkins. She also had major roles in other films like Jerry Maguire and The Boondocks and Southland.
