We got to watch these movies later than in US, with the iron courtain and all. I remember Bruce Lee as very influential for the chinese McDojo business, some of my friends lost a few years trying to learn one inch punch, sticky hands and all that shit. They wised up and moved to fighting sports after a few street beatings.
Steven Segal was also influential in the mcdojo business, but mostly for nerds that were more into japanese culture than fighting anyway, so it wasn't as harmful. It was a lot more niche.
JCV was big also, people had posters in their rooms growing up and t-shirts with" double impact". It got people into KB I guess, though I suspect those who were made for contact sports would've trained in them anyway.
