The ongoing writers` strike in Hollywood has impacted the production of Jennifer Lopez`s `Unstoppable`. According to Deadline, `Unstoppable` was filming in Los Angeles and was disrupted by picketing strikers earlier in the week.

`Unstoppable` is based on the story of Anthony Robles (Jerome), a 3x All-American wrestler born with one leg who prevailed in a national championship at Arizona State. Oscar-winning Argo editor Billy Goldenberg is making his feature directorial debut on Unstoppable. The project is backed by Ben Affleck and Matt Damon`s Artists Equity.
