Mrs. Doubtfire, the 1993 movie, had gone viral after a random post by a movie-trivia Twitter page had disclosed some crucial information about it. In a 2015 interview of the movie director, Chris Columbus, revealed that Robin Williams had improvised so much in the movie that there existed different cuts of the movie, such as an R-rated one, and even an NC-17 one.
People found themselves to be particularly curious about the NC-17 rated version of the movie. What could Robin Williams had performed in the movie that it forced the MPAA to give it the NC-17 rating, was what really made them curious. Columbus revealed that there was a deal between himself and Robin, and that as per the deal:
The reality is that there was a deal between Robin and myself, which was, he’ll do one or two, three scripted takes. And then he would say, ‘Then let me play.’ And we would basically go on anywhere between 15 to 22 takes, I think 22 being the most I remember.
As he revealed the fact that each scene for the movie had several recorded takes, he also talked about how Robin would act way beyond the scope of a PG-13 movie, and that is why there were so many cuts of the movie.
He would sometimes go into territory that wouldn’t be appropriate for a PG-13 movie, but certainly appropriate and hilariously funny for an R-rated film. I only [previously] used the phrase NC-17 as a joke. There could be no NC-17 version of the movie.
While the director is open to a documentary that talks about and reveals certain material of a potentially R-rated movie, but it’d be too much to expect an NC-17 version to simply drop out of nowhere.
I would be open to maybe doing a documentary about the making of the film, and enabling people to see certain scenes re-edited in an R-rated version. The problem is, I don’t recall most of it. I only know what’s in the movie at this point because it’s been a long time. But I do remember it was outrageously funny material.
