The Big Bang Theory is a show that will light up an interest in the field of science inside you. This show is perfect for people who are often regarded to be “weird” just for being smart since it shows us that everyone is different in their way and has nothing to be ashamed about it. Six years have passed since the last episode of The Big Bang Theory was released. So, it’s natural to get intrigued about what the cast is up to now. So, if you are as curious as me, here’s what the cast of The Big Bang Theory is doing now. Some of our favorite characters from the sitcom have changed in appearance since they first appeared in the show, so we have also included ‘then and now’ photos of the cast of The Big Bang Theory.
1. Jim Parsons as Sheldon Cooper
Jim Parsons took up one of the most iconic roles on television, and appeared as Sheldon Cooper in The Big Bang Theory.
