Sisters is due out 12th of December in the UK. Directed by Jason Moore, who made Pitch Perfect, it stars Amy Poehler and Tina Fey as two sisters who throw a final house party before their parents sell of their family home. And, having Tina Fey (Date Night) in the cast does basically mean that it is a comedy.
The film is rated R in the United States, so we are expected to witness some raunchy humour. The script by Paula Pell (Saturday Night Live) also guarantees the rude gags.
