I think JF has said he wouldn't go further than the 30's, but I don't think ageing is the problem, as you can do wonder with good make up. I remember Jeremy Irons playing a 20 years old at the beginning of a movie called The House of Spirits, then at least 60 years old at the end of the movie and it was perfectly credible. I would like to see what the main characters are going to become in 20 years, in 30 years, but only if they can find some interesting storyline of course ! Violet would be dead though
