who played rusty and audrey
Dana Barron as the original Audrey Griswold. Most recently she played a gynecologist in a comedy called 'Happythankyoumoreplease'. It looks pretty good, to be honest, though the name looks like I can't type for crap! In 2006, she directed (and had a role in) National Lampoon's 'Pucked', starring Jon Bon Jovi.
Last year she was in two movies, 'Foreverland' and 'Hick'. At the moment she is filming a movie called 'Open Road' and is in the series 'The Firm'. The pic above is from just a few months ago at the Winter TCA Tour. Johnny Galecki as Rusty. Of course, he's in 'The Big Bang Theory', my son's favorite show.
