Mike Prinke :
It wasIndiana Jones and the Temple of Doom . Or rather , that one was the wheat that broke the camel ’s back .
Most of the movie was distinctive PG dangerous undertaking transportation , no different from the premature Indy movie orStar Wars , but then there were a few worrisome shot like the one where Mola Ram extracts a homo ’s core and give him to Kali . Initially this was hold enough to give it an R paygrade , just as the climactic scene was forRaiders of the Lost Arkbefore it . In that example , all Lucasfilm had to do was obscure Belloq ’s irrupt head with a column of flame to reduce the shock of the scene and they make their PG back , butTemple of Doomwas comparatively a lot more pervasive with things that might have been raise up to young children .

thwarted with this state of affairs and not wanting to irrigate down the movie , directorSteven Spielbergdecided to fence with the MPAA over it . He felt that although some of the activity and repugnance was too intense for children , it was still clearly a work of illusion and , as such , did n’t seem like it should be limit to audience 17 and up .
This was n’t the first motion picture to struggle with this distinction : a whole class of action and revulsion moving picture were emerging that definitely did n’t seem “ matured , ” but still registered complaint for the PG rating being misleading about their level of bloodshed and violence in some scenes ( Joe Dante’sGremlins , which Spielberg produced , was one example ) . So , Spielberg and company go on to suggest that the MPAA needed some form of mediate valuation between PG and R to denote movies appropriate for teenagers but too mature for children .
WhileTemple of Doomitself remained rated PG , leave alone many parents in 1984 rather dismayed , the Modern rating was institute that very class as PG-13 , and was first applied to the movieRed Dawnseveral month after .
