[ed. Fell down the Rabbit Hole this morning reading about de-aging technology (specifically, the new Indiana Jones movie). General consensus seems to be: it works pretty well sometimes but not others (eg. IJ) and has a ways to go before becoming something really seamless and unnoticeable (see also: here). I love these scenes from Martin Scorsese's "The Irishman". First because it's a great movie, second because the acting is wonderful (in Al Pacino's case as union boss Jimmy Hoffa some have said overacting, but I disagree strongly - see for yourself), and third because the anti-aging technology used here is about as good as it gets. Btw, for an example of early anti-aging efforts, see: The Curious Case of Benjamin Button where Brad Pitt's face is simply pasted over those of some babies and children as he grew older/younger. Weird but still a great movie!]
