Opening a movie on Dec. 18 this year might just be suicide. Or brilliant.

Tina Fey and Amy Poehler’s new flick, Sisters, which looks every bit as stupid and funny as it sounds, posted a new promo yesterday, channeling “the Farce.”

Oh, there are Star Wars references here aplenty: Chewbacca, lightsabers and even calling director Jason Moore, “J.J.”

“R2-D2 is my current bra size,” Fey says.

And there is a very special guest appearance at the end which we won’t spoil for you.

Sisters, per the YouTube description, is about “two disconnected sisters summoned home to clean out their childhood bedroom before their parents sell the family house. Looking to recapture their glory days, they throw one final high-school-style party for their classmates, which turns into the cathartic rager that a bunch of ground-down adults really need.”

If you don’t have Star Wars tickets already for opening weekend, you might be left with no other option. They’re marketing this thing with #youcanseethemboth.
