they didn't even try to........
explain the technology behind the invisibility? overall a decent stalker movie. 7/10.
shareOh they did! In a way, at least... at about 15 min in we see the news article on her smartphone about Griffin's death and there it says something about "a technology which calibrated multi-cameras based on refractive projection and ray tracing." (whatever that may be) -- and he "had been planning to launch a 2 billion $ tech venture called OptiPro..."
Although it's not clear whether this is how he made his fortune in the first place (not invisibility-related) and the "suit" was stlll his secret project...
