Newlyweds (2011)

When you get married, you're not just getting a husband or wife-you get the family, the friends, even the exes. Buzzy (Edward Burns) and Katy (Caitlin FitzGerald) are newlyweds. Katy's meddlesome sister Marcia (Marsha Dietlein) has been married to Buzzy's friend Max (Max Baker) for 18 years. As Marcia and Max's marriage is crumbling under the weight of life together as empty-nesters, Buzzy and Katy's honeymoon period is upended when Buzzy's wild-child baby sister shows up at the couple's TriBeCa apartment with more than a little baggage.
