Teisha Lowry "Blondie" trained professionally in Krav Maga for 12 months leading up to filming; a military self-defense and fighting system developed for the Israel Defense Forces (IDF) and Israeli security forces.
Teisha Lowry's character "Blondie" performs a rear naked choke on Derek Zhang's character "Asian Bodyguard" which ended up being quiet dangerous during filming and he became ill from lack of oxygen and complete exhaustion.
The fight scene took 7 weeks of fight rehearsals to perfect and 12 hours to film; non-stop.
