Stuart Fails To Save The Universe Cast Talks Cow Stomachs, Free-Fall Stunts — Plus, Big Bang Theory Star Returns In Episode 6

Episode 6 of "Stuart Fails to Save the Universe" reintroduces a legacy cast member, Raj, played by Kunal Nayyar. Nayyar's character, who was killed off in a post-apocalyptic universe, reappears to remind Stuart that the entire universe is at risk of disappearing within just hundreds of years. The episode features unusual acting notes, such as Raj and Denise lying in bed and chewing cud, while discussing their future together.

Filming those scenes involved extensive wire work, with John Ross Bowie, who weighed significantly less than his co-star, Brian Posehn, receiving the brunt of the physicality. Bowie recounted being dropped 23 feet during a scene, feeling a sense of impending doom and having to maintain his character's smart-ass attitude throughout.

Despite the physical challenges, Bowie found the experience fun and a challenging acting exercise. The episode concludes with Stuart and his companions inadvertently saving Bowie and Kevin Sussman from their free-fall predicament, ultimately ensuring the universe's continued existence.
