Jason Sudeikis and Olivia Wilde went through a highly publicized split six years ago, and new reports have now revealed just how much the split inspired critical moments in the entertainment industry.

The couple’s bitter dissolution reportedly served as a central reference point for an upcoming television project created and written by George Kay.

Sudeikis and Wilde were engaged for seven years until they eventually called it quits in 2020 and embarked on a high-profile custody battle for their children. 

New Drama Draws Inspiration From Jason Sudeikis And Olivia Wilde Breakup Controversies

Sky’s upcoming eight-part divorce drama “War,” created and written by Kay, centers on the devastating split between tech mogul Morgan Henderson, played by Dominic West, and his movie star wife Carla Duval, played by Sienna Miller. 

While Kay noted that the show remains an original story with fictional characters, he admitted to incorporating “little lifts off real life.” According to the Daily Mail, Miller acknowledged the real-world connection, saying, “It’s awful, and it’s based on a real-life event we’re all probably familiar with.”

The creative premise mirrors the breakup between Wilde and Sudeikis, who began dating in 2011, got engaged in 2013, and share two children, Otis and Daisy, before their split led to a protracted custody struggle.

“I think Carla probably thinks that (the divorce) will be a little bit messy, that she’ll get what she asks for. But at that moment, she decides that it’s too late,” Sienna said.

West added that while his character is initially stunned by the incident, it sets off an all-out confrontation, remarking that “what he does on the declares war.” 

Notably, Sky has already renewed “War” for a second season, which will shift into an anthology format focused on a major defamation trial.
