Was the G rating for TMP mandated by Paramount before the start of production? If so, why? If not, how was the decision made along the way to keep within the confines of G? Has anyone come across any documentary evidence one way or the other? I have been critical of TMP's script (or, at least, what ended up on screen) and wonder whether the results would have been less disappointing to me and my cohort if there hadn't been a G constraint. Not that a space battle with phasers would necessarily have resulted.
