As previously reported, during season five of Weeds, viwers will be meeting Nancy's estranged sister.
Now, according to The Hollywood Reporter, we know that Jennifer Jason Leigh has been cast as Jill, Nancy's older sibling.
Leigh is set to appear in at least two episodes next season. Here's how her role will come about:
Nancy sends Andy to take her youngest son, Shane, to go live with Jill out in suburbia. However, when Jill gets fed up with her own suburban family, she'll find herself back in Nancy's life; jealous, frustrated, and intent on having it out with her sister.
