Jennifer Lopez and Ben Affleck's highly anticipated film "Unstoppable" is set to premiere at the Toronto International Film Festival on September 6, but the excitement surrounding the movie is now overshadowed by their recent divorce. Lopez officially filed for divorce from Affleck on Tuesday, marking the end of their two-year marriage. However, the former couple is expected to reunite next month to promote their joint project, a situation that adds an unexpected twist to their separation.

"Unstoppable," which Lopez co-produced alongside her producing partner Elaine Goldsmith-Thomas, is a key project for both stars. The film, which completed filming in January, will have its first screening as part of the Special Presentations section at the Toronto International Film Festival before being released in theaters for a limited run by Amazon MGM Studios in December. With Affleck and his long-time friend Matt Damon among the 14 producers through their production company, Artists Equity, the film is a significant venture for both Lopez and Affleck.

According to a report from the Daily Mail, some of the film's producers are encouraging Lopez and Affleck to "appear together" at the Toronto premiere to boost excitement for the movie. This potential reunion, however, is causing quite a stir given their recent split. The prospect of the two stars sharing the spotlight amid their divorce has sparked speculation and concern over the dynamics at the premiere.

Insiders suggest that there are efforts to manage the situation carefully to avoid any awkward encounters between the former couple during the event. A source quoted by The U.S. Sun hinted at behind-the-scenes maneuvering, stating, "Everyone already knows them being there is going to overshadow it, but clearly neither of them will be keen to cross paths." The tension is palpable as both Lopez and Affleck are known to be intensely private about their personal lives, particularly during such a publicized separation.

Lopez and Affleck's relationship has been one of Hollywood's most talked-about romances, spanning two decades with its ups and downs. After rekindling their romance in 2021, the couple seemed poised for a lasting partnership, but this year saw them quietly drifting apart. The final decision to part ways was made official this week, just as the pair had not been seen together publicly for several months.

An insider speaking to The U.S. Sun commented on the couple's incompatibility, revealing, "Jennifer and Ben are over, they're just not compatible — even after 20 years neither have changed." The source further elaborated on the differences that drove them apart, noting Affleck's struggles with alcohol and Lopez's commitment to a clean-living lifestyle. "He's had his demons with alcohol, but she doesn't really drink or smoke. She's super clean-living. Both are very difficult human beings," the source added.

The timing of Lopez's divorce filing on their second wedding anniversary is seen by many as a bold and symbolic gesture. An anonymous source told Page Six that Lopez's decision to initiate the divorce on this particular date was meant to convey that she is "a woman standing up in her own way." This move underscores her desire to take control of her narrative, especially in the wake of a highly publicized relationship.

Lopez further emphasized her independence by filing the divorce papers "pro se," meaning she is representing herself in the proceedings without a lawyer. This decision is seen as a powerful statement of self-reliance and determination as she navigates this new chapter in her life.
