The notion of using software to censor pritzus in movies is hilarious. It’s like trying to find loopholes that would allow the movies to be considered kosher. If the director/screenwriter felt that pritzus, or simply shtus, was integral to their story, then the whole film is shtus, isn’t it?
I would support an effort to provide hechshers for truly wholesome and heimeshe films, assuming we can allow ourselves a little entertainment. It would be more kosher than watching sports where you can’t avoid the pritzus.
