Bob Newhart’s memorable appearance in NCIS before he graced The Big Bang Theory
Throughout its long run, the police procedural drama, NCIS has featured a number of celebrity cameo roles, with entertainment legend Bob Newhart making an appearance in Season 8.
The actor took on the role of Dr. Walter Magnus in the season 8 episode titled, Recruited, which followed the investigation into the mysterious death of United States Navy recruiter Simon Craig.
Following his introduction in the episode, Dr. Magnus is revealed to have been diagnosed with Alzheimer’s disease. Despite his deep awareness of how the illness is slowly affecting his memory, he does his best to assist the NCIS team, offering valuable insights even as his condition worsens.
Newhart’s portrayal of Dr. Magnus was both touching and impactful. Though his screen time was brief, he brought immense heart and depth to the character.
While the character of Dr. Magnus eventually returned to the show in the Season 18 episode titled, Everything Starts Somewhere, Newhart sadly passed away on July 18, 2024. The character was later portrayed by Thomas Crawford.
Despite his short time on the show, Newhart’s performance left a lasting impression on NCIS fans, who continue to reflect on his heartfelt appearance long after the episode aired.
Bob Newhart had two conditions to star in The Big Bang Theory
Bob Newhart had a memorable recurring role as Professor Proton (Arthur Jeffries) in the hit sitcom The Big Bang Theory, a character he later reprised in its spin-off, Young Sheldon. In a past interview, the legendary comedian revealed that he had two key conditions before agreeing to join the show.
Speaking with The Hollywood Reporter, Newhart shared that he had been familiar with the show creator Chuck Lorre’s work and the two had wanted to collaborate for some time.
“We’ve been going back and forth, and we never could find a project that we could both agree on until The Big Bang Theory,” he said before explaining his two non-negotiable requests.
“I had only two things that were paramount: No. 1, my scenes had to be taped live,” he said before adding, “No. 2, I wanted it to be a semi-recurring role.”
He emphasized his love for performing in front of a live audience, stating, “I always felt that the live audience gives it adrenaline. That’s the only way I function.” And Lorre fully agreed to these conditions, allowing Newhart to bring his signature comedic style to the show.
Newhart had an incredible experience working on the series and spoke highly of the cast and writing, saying, “The Big Bang Theory is well written and it has an incredible cast.”
His performance as Professor Proton, a childhood science hero to Sheldon Cooper, not only won over longtime fans but also introduced him to an entirely new generation of viewers.
Newhart made a total of six appearances on The Big Bang Theory, following his introduction in Season 6. His portrayal was so well received that it earned him a Primetime Emmy Award for Outstanding Guest Actor in a Comedy Series, marking a well-deserved recognition of his comedic brilliance.
