If only John Travolta had aged as well (he looks more and more like an aged Eddie Munster every day). Come to think of it, a lot of the actors I had a crush on haven't faired so well: Val Kilmer, Tom Hanks, Don Johnson, James Spader and Judd Nelson. (visit here for some fun then and now images).
Oh, and I have to give special mention to one guy who definitely blossomed late in life... Patrick Dempsey. Who would have ever thought, even though I did love Can't Buy Me Love. John Cusack is another example. He looks so much better now. Did those two make a deal with the devil or something?
What star from your childhood still looks good?
Since I did mention Grease 2, Michelle Pfieffer still looks amazing.
