I’m trying to remember this movie. It wasn’t a very popular movie if I’m remembering correctly. It was about this family who was on the run from the government (not sure which institution or why). The son was a then 80s heartthrob if I’m remembering correctly. There were two G-Men chasing them and I think one of them gave a speech about government mistrust. It turns out the G-Men were some sort of man-made mutants/monsters. Their real identity was revealed to the boy at some point in some sort of standoff.
