Stephen Hawking – Himself
Stephen Hawking appeared in seven episodes of The Big Bang Theory between 2012 to 2017. We can say Sheldon was highly pleased as he got the chance to meet his hero and, of course, those episodes are worth remembering.
For a fact, Hawking’s science-based works have done a lot as t relate to world theories. We don’t need to tell you that.
Dean Norris – Colonel Richard Williams
We have seen Dean Norris in a lot of exceptional films such as Total Recall, Lethal Weapon, Evan Almighty, and Terminator 2: Judgment Day.
However, he has a higher rating perhaps on Breaking Bad as DEA agent Hank Schrader and on Under the Dome as councilman “Big Jim Rennie. Colonel Richard Williams appeared as Colonel Richard Williams On The Big Bang Theory.
