I’m presuming that The Irishman director Martin Scorsese wanted to de-age Robert De Niro and others in a way that was significantly more realistic than the Michael Douglas de-aging in Ant Man and the Wasp.
I actually had no problems with the Douglas de-aging, but then I’m not really familiar with how good or exacting de-aging technology can be these days. It’s advanced significantly, I’m guessing, over the last five years.
BTW: A major film festival announcement regarding Scorsese and The Irishman is imminent. I’m not the only one who’s been presuming all along that Scorsese’s period crime film would premiere at the New York Film Festival (9.27 to 10.3) because of his longstanding friendship and alliance with NYFF honcho Kent Jones. But who knows? Perhaps another festival or two will figure into things. Just a matter of sitting tight.
