Stars Wars: The Force Awakens isn’t the only winter movie with plenty of nifty special effects: According to a new featurette, Sistersyou know, the comedy starring Amy Poehler and Tina Fey as siblings throwing one last party together — also utilizes new technology like “practical vomit effects,” according to Ike Barinholtz.

The clip features interviews with Poehler, Fey, Barinholtz, and Maya Rudolph talking about the “magical” experience of making the film. “It could not be more exciting to see the way that technology has evolved, and yet, keeping one foot in the pre-digital world,” Poehler says at one point in a British accent before Fey admits that they’re just using British accents to “cover [their] buzz.”

Watch the clip, which also includes a George Takei cameo and some diva moments from Rudolph, above, and see Sisters when it arrives in theaters Dec. 18.
