I wonder how they progressed her to Jessica's real age of fourteen?

It happens a lot. Some actors in Beverly Hills 90210 were in the 30s i think.

I LOVED 'Girls Just Want To Have Fun'. Was very funny and entertaining.

I can't comment on this movie since I haven't seen it yet but I also found it funny that Hunt played Kathleen Turner's daughter in "Peggy Sue Got Married". Even back then I assumed they were sisters at first.
