Who plays Dr. Pemberton and Dr. Campbell on the Big Bang Theory cast? Sean Astin and Kal Penn guest star

Actors Sean Astin and Kal Penn are joining the Big Bang Theory cast for a new episode of the show.

In the new episode, Sheldon (played by Jim Parsons) and Amy (Mayim Bialik) find out that their super asymmetry theory has been proven by two physicists. Some drama arises when they want to remove Amy from a Nobel prize nomination.

Having two very recognizable actors join the cast is going to make for an interesting episode, especially since Astin and Penn look like they are going to be hilarious. A sneak peek from the new episode is shared below to get a feeling for the characters of Dr. Pemberton and Dr. Campbell.

Who plays Dr. Pemberton and Dr. Campbell on the Big Bang Theory cast?

Actor Sean Astin was recently seen as a main character for Season 2 of Stranger Things. He has been acting since he was a kid, with early roles in classic such as The Goonies. Astin also starred in Rudy and played Samwise Gamgee in The Lord of the Rings.

Kal Penn played Dr. Lawrence Kutner for years on the Fox drama, House. He also has a lot of fans for his role as Taj in National Lampoon’s Van Wilder and as Kumar in the trilogy of Harold & Kumar films.

Bringing on Sean Astin and Kal Pen as Dr. Pemberton and Dr. Campbell on The Big Bang Theory cast was a great decision for the final season of the show. Will they put a wedge in the relationship between Sheldon and Amy?

The episodes are ticking off until The Big Bang Theory airs its series finale this spring. Season 12 is the final one for the hit CBS comedy, making each episode really important.

In addition to the main story from the new episode, a sub story revolves around Bernadette (Melissa Rauch) finding success at her job.

The Big Bang Theory airs Thursday nights at 8/7c on CBS.
