As fans know, Mr. Big was Carrie Bradshaw's (Sarah Jessica Parker) love interest throughout the series' six seasons. They married in the first film adaptation and were still a couple by the end of the 2010 sequel.
Although it is unclear how the character's absence will be explained, a script for the third "SATC" movie revealed Mr. Big died of a heart attack early in the film with Carrie grappling with grief for the rest of it.
Back in 2018, Noth reacted to the news of his untimely demise for the final theatrical bow, calling the script "superior" to the first two.
"I really hate corny stuff and it could be because I'm a little bit of a cynic," he revealed on the "Origins" podcast. "Like, the whole thing at the end of the (2008) movie in the shoe closet -- hated it. Hated the thing at the end of the movie after I felt she deceived me and then I say, 'Well, it's time I give you a bigger diamond ring.' Hated it."
