Well, first of all, Dan will have to play 37 NOT 97.

It's not that hard to make a young person in their 20's
look old. You simply give them shadows under their
eyes, highlight the creases alongside their mouth,
and highlight the wrinkles on their forehead and 
alongside their eyes. Add a touch of gray hair and
you are done.

A 37 year old is still a moderately young person.

Now, making an older person look young is more
difficult but it too can be done. One technique,
in addition to heavy make-up, is to use Tape to
pull back the skin on their face, similar to a 
face lift, then cover the tape with a wig. 

I don't see a problem with Dan playing age 37,
but Alan Rickman playing age 20 is going to be
very difficult. Though another technique is to
shoot through gauze, that is frequently used for
glamor shots to soften wrinkles. Keep in mind
the scene of Rickman/Snape at age 20 are in 
memories and they can dream-like and can easily 
be shot as softly lite, gauze filtered scenes.

My problem isn't /can/ they do this, but /will/
they do it?
