The movie Rockaway is not a true story. It's a creation of the filmmakers' imagination, with elements crafted to entertain and engage the audience rather than being based on real events.
Again, without knowing the specific story, it's hard to say. But if it's a historical account, key elements might include important dates, like when certain buildings were built or events occurred in Rockaway.
I'm not sure specifically which 'Rockaway True Story' you're referring to. There could be many stories related to Rockaway. It might be a local legend, a personal account from someone in Rockaway, or something else entirely.
