The last time we saw Tina Fey and Amy Poehler on the big screen, they were in Baby Mama (2008), where Fey played the no-nonsense businesswoman looking for a surrogate — none other than Poehler, who plays the scheming white trash Angie. Of course, you also know these Saturday Night Live (SNL) favourites from their three stints as emcees of the Golden Globe Awards. In Sisters, which will hit cinemas here next week, the duo reunite playing the Ellis siblings who are summoned home to clean out their childhood bedroom. It's a reversal of roles from Baby Mama — this time, Fey plays the wayward sister, while Poehler takes on the role of the responsible one.

Written by Paula Pell, who co-wrote some of the most iconic sketches and characters in SNL's history,
Sisters is bound to be a hilarious look at reliving your youth as mature, responsible adults. Here's what you didn't know about the production:

Tina Fey

1.     The movie's inspired by a real-life story.
The root of the movie started when writer Pell recounted how different her sister's journal's and hers were. "She was very foxy and tall and all the boys loved her, while I was very short and matronly and looked like I was 50 at 13.  Her journal was always like: 'Oh my God, I made out with Bill.'  Mine was: 'I changed the grit on my rock tumbler in my science kit!'"

2.     Both Amy Poehler and Tina Fey don't have sisters in real life.
"I jumped at the chance to play Tina's sister on film, because we serve as chosen sisters for each other," gushes Poehler. "I've known Tina 20 years, and she's the closest thing I have to one. It was exciting to get the chance to play that on screen."

3.    
Sisters is an SNL-lover's dream.
Some of SNL's favourite comedians feature in the film. There's Bobby Moynihan who plays try-hard Alex, Maya Rudolph who's cast as the high school bitch and Kate McKinnon who takes on the role as a lesbian friend.

4.     There's a little bit of the real teenage lives of Poehler and Fey in there.
Like every room set in a teen movie (although it's been billed as a "teen party movie, with adults"), the Ellis girls' bedroom is adorned with teen memorabilia. Poehler also contributed to the props: An Out of Africa poster can be spotted — a film the comedian was obsessed with as a teen.

5.     It's not just a raunchy, dirty comedy.
According to Fey, the core of the movie is about letting go of who you were in your youth. "It's okay if you want to be someone different now, and it's okay to grow up," she lamented. 

Sisters will be released in local cinemas on 17 March. Rating: NC16 – Sexual Humour and Drug use. © 2016 Universal Studios
