No Retreat No Surrender (1985) was at the time a rare hybrid of Hong Kong and U.S.A.– an attempt to bring Asian Martial Arts movies to American audiences. It was written by Keith Strandberg and directed by Corey Yuen (Dragons Forever, Yes, Madam) in his English language debut. (Yuen would go on to have a successful career in the west from No Retreat 2 to working on Jet Li‘s American movies like Lethal Weapon 4, Romeo Must Die & The Expendables as well as effectively launching Jason Statham as an action star with The Transporter.) It also notably had remaining vestiges of 70s Bruceploitation genre by inexplicably having a main character being trained by a ghost of Bruce Lee (Kim Tai-Chung aka Tong Lung.)

Directed by Oliver Harper (In Search of the Last Action Heroes) documentary features interviews not only with the likes of No Retreat producer Ng See-yuen, original cast members such as Kurt McKinney, J.W. Fails, Peter “Sugarfoot” Cunningham as well as sequel’s Cynthia Rothrock and Matthias Hues but also with famous fans such as Scott Adkins(Undisputed, Ninja). The only one missing is The Muscles from Brussels himself, Mr. Van Damme.
As of now movie is over 40% financed on Kickstarter and if you want you can pre- order it right here. I have no doubt this will get to 100% in no time.
