To have a good time the film’s thirtieth anniversary in 2023, director Chris Columbus mentioned Robin’s genius improv on the Mrs. Doubtfire set, saying they needed to have 4 cameras going without delay to you should definitely catch his unscripted moments.
In an interview with Enterprise Insider, he recalled, “Early on within the course of, he went to me, ‘Hey boss, the best way I wish to work, if you happen to’re up for it, is I will offer you three or 4 scripted takes, after which let’s play.’ By saying that, what he meant was he wished to improvise. And that is precisely how we shot each scene. We might have precisely what was scripted, after which Robin would go off, and it was one thing to behold.”
