 We filmed those scenes on Lacy Street, in a slummy area of old wooden buildings that could pass for Brooklyn.Whilst on the production set, Seagal claimed that due to his Aikido training, he was 'immune' to being choked unconscious.It has been alleged that at some point Gene LeBell (who was a stunt coordinator for the movie) heard about the claim, and gave Seagal the opportunity to prove it.
