Amy Poehler, Tina Fey Debut 'Sisters' Trailer on 'Jimmy Fallon'

Weekend Update co-anchors also play a round of True Confessions on 'Tonight Show'

The Tonight Show staged a mini-Saturday Night Live reunion Tuesday as Jimmy Fallon invited his fellow Weekend Update anchors Tina Fey and Amy Poehler to debut the trailer for their new comedy Sisters. In the film, Poehler and Fey play sisters who, after learning their parents sold their childhood home, decide to throw one last party at the house. "If you like us and you like sisters and you like us playing sisters, you're gonna love Sisters," Poehler told The Tonight Show crowd. Sisters is due out December 18th.

Fey and Poehler last appeared on the big screen together for 2007's Baby Mama. Sisters is the first feature-length screenplay from longtime SNL writer Paula Pell, who also worked on Fey's 30 Rock. The film co-stars Ike Barinholtz, former Daily Show correspondent Samantha Bee and SNL vets Maya Rudolph, Bobby Moynihan, Kate McKinnon and Rachel Dratch. WWE star John Cena also shows up in the trailer as, surprisingly, Fey's love interest whose safe word is "Keep going."

In addition to unveiling the Sisters trailer, Fey and Poehler joined Fallon for a game of True Confessions, where the contestants must guess whether the contents of two envelopes – one with a genuinely weird story, the other with a genuinely fake story – are true or false. During Fey's turn, the actress tries to convince everyone that she was once mistaken as a prostitute in Monaco, while Poehler reminisces about the time she helped Yoko Ono cross the street. However, Fallon shares the craziest story: Getting robbed by a drug dealer with a sawed-off shotgun in college.

After their Tonight Show appearance, the official, slightly NSFTV Sisters trailer was posted. Check out that full-length preview below:
