Sylvester Stallone is one of the biggest Hollywood action stars in Hollywood history. While he has appeared in innumerable of the industry's biggest franchises over the years, two of them in particular – the Rambo and Rocky series – cemented his status as a bonafide action star.

With a career that spans half a century, Stallone has a story to tell – one that is worth hearing. And in what has become the norm for the streamer, Netflix is spearheading the project.

On June 30, we got our first-ever peek at the upcoming documentary with a short teaser trailer released to the company's YouTube page.

Although it's less than a minute in length the trailer teases a candid Stallone. It opens with a shot of the 76-year-old actor looking on in his characteristic gruff manner. Alongside this shot, we hear him say, "Do I have regrets? Hell yeah, I have regrets."

Over the next few seconds, we see multiple shots of the actor at different locations and hear him say, "What is healthier? To live under the illusion that you could have been great, or actually have an opportunity to be great and then you blow it and you realize you're a failure?"
