Kristen Wiig and Bill Hader reunite for the film 'The Skeleton Twins'

Kristen Wiig and Bill Hader star as siblings in the movie 'The Skeleton Twins,' which debuts in September. Kristen Wiig recently starred in 'Anchorman 2: The Legend Continues.'

“Saturday Night Live” stars Kristen Wiig and Bill Hader are reuniting for the upcoming film “The Skeleton Twins,” which follows siblings who get to know one another again after a long time apart.

In the movie, Milo (Hader) goes to live with his sister Maggie (Wiig) and Maggie’s husband Lance (Luke Wilson) after a long estrangement between the brother and sister. The film also stars “Modern Family” actor Ty Burrell and Joanna Gleason of “Blue Bloods.”

Wiig and Hader joined “Saturday Night Live” in 2005, with Wiig departing in 2012. Hader left the show in 2013. 

Wiig recently lent her voice to this summer's movie "How to Train Your Dragon 2" and starred in the IFC miniseries "The Spoils of Babylon," for which she received an Emmy nomination for Outstanding Lead Actress in a Miniseries or Movie. She also recently starred in the 2013 film “Anchorman 2: The Legend Continues." Meanwhile, Hader recently appeared in this summer's film "22 Jump Street" and has guest-starred on the Fox series "Bob's Burgers" and "The Mindy Project." Away from "SNL," audiences may remember them most together as a married couple in the 2009 movie "Adventureland."

Wiig recently spoke with Elle about being only thought of as a comedian from “Saturday Night Live.”

“It’s not necessarily a bad thing,” she said of being put in a comedy niche. “You have to have some sort of context for a person to register in your brain, and I was introduced to the world as a cast member of 'SNL.' But I’ve always wanted to do dramatic stuff, to write and direct, do a lot of different things. Comedy is where my heart lies, but there’s also something really satisfying about being able to step away with a small crew, become a character and get to know her for a few months at a time.” 

When it debuted at various festivals, including the Sundance Film Festival, “Skeleton” received mostly positive reviews, with Variety critic Geoff Berkshire writing that “the biggest surprise for audiences expecting plenty of laughs will be just how effectively both thesps handle the weightier dramatic material in the screenplay… ‘The Skeleton Twins’ captures the way siblings develop their own unique comedic shorthands in a way few films ever have.” David Rooney of The Hollywood Reporter said the film is “warm, funny, heartfelt and even uplifting. The film is led by revelatory performances from Bill Hader and Kristen Wiig, both of them exploring rewarding new dramatic range without neglecting their mad comedic skills.” 

“The Skeleton Twins” hits theaters on Sept. 19.
