Movie scaling

1

I have a client who wants a website that is 100%x100% 3-column(which is fine, done all that stuff with css/html). My problem is, he wants a flash intro in the middle column which is scalable to stretch the entire middle column. I was wondering, is there any way to make a flash move scale to fit a css div? I will need both height and width to change so it will fit most resolutions
