AceShowbiz - Amidst their high-profiled split, Ben Affleck's role in Jennifer Lopez's documentary, "The Greatest Love Story Never Told", has come under intense scrutiny. Sources close to the couple have disclosed to PEOPLE and other outlets that Affleck was not just a passive participant but a significant driving force behind the project.

Multiple insiders revealed that Affleck, 52, was intimately involved in the creative process for the Prime Video documentary, which documented their rekindled romance and subsequent marriage. "He was the one who had control, pretty much," a source conveyed to PEOPLE, further emphasizing his pivotal role. Affleck's input was substantial, from ideation to editing, contradicting the on-screen narrative of his hesitancy.

The documentary debuted alongside Lopez's projects "This Is Me...Now: A Love Story" and a corresponding music album in February. "He was very much in favor of the project, and he was a driving force for [Lopez] to do the movie and the album and then he insisted on the documentary," an insider noted.

However, this contrasts starkly with the impression left on viewers that Affleck was reluctantly involved.

Reportedly, Affleck's company, Artists Equity, conceived the documentary idea. Lopez's team was initially reluctant, preferring to focus on her album and Amazon original video project. Despite reports of Affleck's discomfort with the exposure, he was deeply involved in editing the film to ensure it projected the narrative he wanted.

"He loved the movie and album, but when you look at the doc, it looks like he's surprised by it and not signing up for it," another source explained. Affleck was "playing the role of playing the regular guy," while in reality, he was the documentary's "engine." These revelations paint a complex picture of Affleck's dual roles - both supportive partner and creative mind behind the project.

Lopez filed for divorce on August 20, marking the second anniversary of their Georgia wedding. Initially, rumors suggested Affleck was uncomfortable with the public nature of their relationship. However, insiders now argue that he encouraged and supported this public life throughout their marriage, further complicating the narrative.

As both stars navigate their separate paths, their intertwined legacies and the documentary they created stand as a testament to a romance that captivated the world - no matter how complex the behind-the-scenes story may have been.
