The only Janie character I know was in She's All That-- Rachel Leigh Cook.
I suck at these games!!

And now that I think about it, I think the characters name was L(L!)anie.

Betty Warren was Kirsten Dunst in Mona Lisa Smile
Pam Dawson was Winona Ryder in Mr. Deeds (again, I only know this because I saw a few minutes of this on TBS the other day)

I don't know the others, but I will have to guess - Little Women?

good guess whiplash! such a smart banana! hahaha
john rolfe was new world (christian bale)
father kiernan was stigmata (gabriel byrne)
janie basdin was american president (samantha mathis)

At first, I was like "'Smart banana?' What the hell is she talking about?!"

And then I realized that my avatar is a banana. Time for your coffee, Whip!

haha when you change your avy and someone looks at this they are gonna be like wtf! hahaha i just laughed cause i imagined your expression at smart banana! hahaha lol!
