Brian Posehn explains to ET's Cassie DiLaura why fans of 'The Big Bang Theory' might not be ready for its new action-packed spin-off, 'Stuart Fails to Save the Universe,' ahead of its July 23 debut on HBO Max. The comedian explains why he was immediately on board when creator Chuck Lorre called him about coming back as Bert Kibbler on the new show, and reveals why this spin-off is so much harder to shoot than the OG 'BBT.'
