Does she know Speed Racer from the recent (awesome) movie? If so that doesn't count for retro points.
Also I think knowing Han Solo is a Star Guy is decent.
My friend has a 19 year old girlfriend who doesn't know Terminator, uh ha and pretty much any movie, tv show, or game named. You even mentioned a couple anime, oh man, anime, that's extra points there alone.
