Sylvester Stallone documentary Sly teaser is out 

On Friday, Netflix dropped the teaser of the upcoming documentary about the veteran actor-filmmaker Sylvester Stallone, titled Sly.  Directed by Thom Zimny and produced by Sean Stuart, the documentary will begin to stream in November.

The film's official logline read, "For nearly 50 years, Sylvester Stallone has entertained millions with iconic characters and blockbuster franchises, from Rocky to Rambo to The Expendables. This retrospective documentary offers an intimate look at the Oscar-nominated actor-writer-director-producer, paralleling his inspirational underdog story with the indelible characters he has brought to life."

Here is the teaser 

The teaser opens with the veteran replying to a question, saying he has regrets. Then he asks, "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?" The brief teaser also features old video footage and images of the Rocky actor.
