Could be, then could be not. There were no movies yet in the 17th and 18th Centuries and yet there were widespread violence bought about by the exploration and eventual colonization of the East. Maybe there is something about how Man lives, his beliefs, his wants...and these might serve as motivation for him to eventually view violence as a necessary "last-resort" option when negotiation fails, or diplomacy fails. Movies only highlight this fact. But they may also spawn violence in the sense that movies transform acts of violence to "iconic" status, worthy of emulation. Then again these are just but theories...
