I think eXistenZ is the perfect example of a biopunk movie. But would you also consider it to be cyberpunk? The majority of the movie takes place inside a virtual reality video game but there actually aren’t many cyberpunk visuals. And while it does rely on new technology to access this virtual world, that technology is primarily biological.

This is the best trailer I could find but it’s pretty low quality. You can watch it on Pluto or kanopy if you’ve never seen it.
