The Big Bang Theory Cast: Where Are They Now?

Between September 2007 and May 2019, The Big Bang Theory delivered 279 episodes across 12 seasons, becoming one of the greatest sitcoms of the modern generation. TBBT gave us a slew of memorable characters from both the starring and supporting cast, the majority of whom were immensely relatable.

Originally starting off with its main ensemble of Sheldon, Leonard, Howard, Raj, and Penny, the show would go on to enlist several terrific actors to play additional major roles which would be added later on in the show's history. While the majority of these characters fell under the geek stereotype, they each came with their own unique qualities, which is what helped the show reach peak success throughout its storied tenure on our screens.

It's often difficult to explain to a new fan just how many layers each character has. Just when you think you've got the gist of someone, a new layer is peeled back to further develop their individual arc within the show. Considering the show was producing new content for 12 years, it was necessary for the characters to go through major changes every now and again.

It's now been a year since the finale so just what has the cast gotten up to since?

Minor characters are an extremely important factor when it comes to making a sitcom as outstanding as can be. What better way to incorporate one of these lesser appreciated names than by having him marry one of the main five characters?

Brian Thomas Smith's portrayal of the ditzy Zack Johnson made for joyful watching, particularly when he was in scenes with the often too smart group of four. First appearing in The Lunar Excitation towards the end of the third season, Zack becomes the on-again, off-again boyfriend of Penny, who ends up becoming his wife following a drunk wedding ceremony they partook in, which was mentioned during season seven's Thanksgiving episode.

After his last official TBBT appearance in the final season, Brian has remained on our screens in small roles, most notably in the 2019 film Babysplitters under the role of Dr Palmer. Aside from this, Smith hasn't been seen too much on television, appearing in just one episode each of The Neighborhood and 9-1-1: Lone Star as Ed and Andrew Reynolds respectively.

His IMDB page also indicates Brian will be appearing in the drama Big Muddy under the guise of Bo Bartlett, which his due for a September release, alongside his role as Christopher in UDrive Me. The new comedy series is currently in the pre-production stage, and everything going on in the world right now, there's no word yet on when work can continue.
