While we couldn't imagine anyone but Chris Noth in the role of Sex and the City's Mr Big, Alec Baldwin was originally up for the gig. Darren Star, the brains behind the show, spoke to Entertainment Weekly recently and said that Alec was his first choice for the part of Mr Big. Darren said that at the beginning, he thought that Alec would be the perfect fit for the playboy character. Alec Baldwin could have played Mr Big... However, after meeting Chris, Darren changed his mind and offered him the part. Chatting to the publication, the producer explained: "I met with Chris Noth and thought he was perfect. "I remember the first table read, how good he was. "I’m not saying that Chris was Mr. Big, but he brought a lot of his own persona to the role". Aidan Quinn was in the mix for the role of Aidan As if that wasn't enough to take in, the SATC creator said that Aidan Quinn was the actor who came to mind when he was casting the part of Aidan. "We initially were thinking about Aidan Quinn for Aidan, but I think he wasn’t available," said the show's creator. John Corbett had featured in a show called Northern Exposure and his "laconic dudish vibe" allowed him to slot perfectly into Aidan's role. Between this and the news that Lisa Edelstein could have played Carrie, it could have been a VERY different show.
