The Big Bang Theory Character Marisa Tomei Almost Played
Imagine an alternate universe where Marisa Tomei, the Oscar-winning actress known for her roles in
and as Aunt May in the Marvel Cinematic Universe, starred as Penny in . While it's hard to picture anyone other than Kaley Cuoco in that iconic role, Tomei almost brought her own spin to the character. Yes, she auditioned for the part of Penny, then called Katie, before the show's pilot ever hit the screen. This twist in casting history sheds light on how close the series came to looking quite different.
Fans of are no strangers to the show's complex casting history.
Initially, the character of Penny wasn't even named Penny; she was called Katie, a role that was originally filled by Jodi Lyn O'Keefe before being recast. Kaley Cuoco, known for her bubbly charm, eventually landed the role, but not before Tomei threw her hat in the ring. In 2022, Tomei revealed in an interview that she found the script intriguing and auditioned, even reading scenes with Jim Parsons, who had already been cast as Sheldon Cooper. Jim Parsons himself reminisced about this unusual audition process, noting how surreal it felt to be part of someone else's audition.
He shared with humor, "Oh my gosh, what a different world that would have been."
Despite the intrigue and positive reception from those behind the scenes, Marisa Tomei decided the role wasn’t the right fit for her at the time. In her reflections, she mentioned that while she loved the script's dynamic and found the premise fascinating, she didn't foresee the show becoming such a long-lasting cultural phenomenon.
Tomei, already an established film star by then, might have been reluctant to commit to a role that could tie her to a sitcom for years. And considering that ran for twelve seasons, her hesitation seems understandable. “I didn’t know it would go on for that long,” Tomei said, adding that she appreciated the show’s concept but ultimately felt it wasn’t the right choice.
One of the more humorous aspects of this casting saga comes from Jim Parsons, who expressed his surprise at being involved in Tomei’s audition process.
Parsons, already cast as Sheldon at the time, found it strange to be reading scenes with another actor vying for a different role. He jokingly recalled how the casting directors hinted that Tomei’s audition also served as a test for his chemistry with potential co-stars. Parsons mused about the alternate reality where Tomei might have played Penny, a thought that amused him as much as fans when the story surfaced in Jessica Radloff's book, .
Had Tomei taken the role, the show might have had a vastly different tone, especially considering the contrast between her acting style and Cuoco's more effervescent energy. Cuoco's iteration of Penny became beloved for her wit and down-to-earth charm, serving as a counterbalance to the eccentric scientists around her. Her portrayal helped shape the series into a massive hit, and she eventually became synonymous with the character.
Despite missing out on the sitcom role, Tomei continued to thrive in her film career, taking on acclaimed roles in , , and joining the Marvel Cinematic Universe as the new Aunt May.
It’s fun for fans to speculate on what might have been like with Tomei as Penny. Would her take on the character have led to a different dynamic with Sheldon, Leonard, and the gang? Some argue that Tomei's more mature and layered approach could have brought a unique flavor to the early seasons of the show.
Yet, it's clear that the decision to go with Cuoco paid off in the long run, as she became an integral part of the show's success and its emotional core.
Even without , Marisa Tomei carved out a niche for herself in Hollywood. By 2007, the same year the show premiered, she was back in the Oscar race for and soon entered the superhero world with
. Meanwhile, Kaley Cuoco's portrayal of Penny won over audiences, making her a household name. The world may never know what with Tomei would have been like, but it's safe to say both actresses found the roles that suited them best.
