How The Big Bang Theory Cast Changed Since Season One: CBS
Some of the The Big Bang Theory actors and actresses look different IRL compared to their characters on the show, but even their characters have evolved over time as the show progressed. Let's remember all of the good times and take a look at how the cast has changed since the show premiered compared to now.
Wil Wheaton is an interesting one because the actor is playing a fictionalized version of himself. That pretty much means that whatever makeovers the actor has in real life are reflected in the character. Wil came in during season three as a reoccurring character and he has continued to pop up now and again. He's another one who isn't going to quit his graphic T-shirt obsession. But, he has switched up his appearance. As time has gone on, his beard and hair have gotten longer.
