This project has been going on for a fair few years now. This is that last teaser before release.
Empire Director Luke Stiles interveiw with New York times;
"unlike movies like MASH, Macaframa and The Revival, Empire would focus more on the personalities of the handful of riders. “Mash is awesome, but all you have is the individual riders’ styles to tell them apart. Almost no one talks. There aren’t any shenanigans or hijinks,” he said. “I’m just trying to capture some of that stuff.”
Pretty sure its release is Bike Film Fest New York this year. Its taken them years putting it together. Should see it available not long after BFF, so i am August.
