The "Top of the Lake" star dishes on the miniseries and what the end of "Mad Men" will be like for her
On being the lead in the Sundance Channel miniseries "Top of the Lake": "I suppose it's the first time I've been No. 1 on the call sheet. I frankly just had so much to do -- I was working, I think, 65 or 66 days out of the 82 shooting days, and 50 of those days were in a row. So it was definitely a bigger venture than I've ever done."
