At first sight, this sounds a bit like a joke. A rich joke. In a future movie, the role of the aging French female billionaire Liliane Bettencourt would be played by the great male actor Jean Rochefort.
Superficially, I can't see how this could be done convincingly, since Madame Bettencourt has a protruding broad and short lower face like a Cro-Magnon, whereas Rochefort looks like a lean-faced British lord. But makeup (with Oréal products, of course) might do the trick in creating an illusion of similarity. Ever since James Cameron's Avatar, we know that anything is possible.
BREAKING NEWS: The French legal system has just announced that it intends to examine a request by Françoise Meyers-Bettencourt to have her mother placed in the care and supervision of a guardian. Jeez, I wish I had so much money that my daughter would seek to take out a court order preventing me from spending it on wine, women and song… or rather—as they say nowadays—on beer and sex and drugs and rock-and-roll. No, I'm joking. I prefer by far being penniless yet sufficiently lucid to have found a nasty way of describing (above) the lovely face of that nice old lady. It goes without saying that, if the future caretaker of Madame Oréal were to ask me to remove my Cro-Magnon remark, I would gladly do so immediately... without even insisting upon a small cash fee (which could be paid into my account out in Australia).
