For one thing Harrison has been making films constantly since 1983 so obviously he is more recognisable we never stop seeing him.

As a career actor he has to look ready to work infront of a camera all the time.

Carrie has made more or less a handful of films since ROTJ.

She is an authoress and public speaker and doesn't have Harrison's constant work out routine.

If you compare her young and old pictures with young old pictures of other actresses playing roles in the field it's obviously the same woman and fits into their number.

None of this line of speaking makes a particle of sense to me.

It's just the cultural bias against mature women all over again.

Sean Connery is still claimed to be sexy and if he hadn't chose to retire would still be in demand but the best Tippi Hedren can hope for is the occasional telly comedy role.

Kathleen Turner doesn't look as conventionally attractive as she did in the eighties (as much due to illness as passage of time) but she is still an amazing actress who she doesn't get enough work and like Carrie looks like herself but older.
