The sound-effect that greets Lucas Lee's flying kick of Scott after he defeats the seven stunt doubles is taken from Tekken 5, as confirmed in the end credits. The backdrop of Toronto behind the fight itself is an in-joke to the fact that usually in films Toronto where this film is based stands in as a substitute to the New York. A further in-joke comes when Lee kicks Scott through the backdrop, going through the CN tower. Usually in the CN tower has to be removed in post-production to not give away New York as actually Toronto, rather than New York.
