In Lynn Shelton’s charming new comedy Your Sister’s Sister, Mark Duplass finds himself sorting through his romantic complications with sisters Emily Blunt and Rosemarie DeWitt … but wait! How can those two play siblings with such an obvious disparity in accents? Well, in this exclusive clip for the movie (due out June 15), their characters explain the whole situation, and then Duplass uses the opportunity to tease Blunt for lovin’ and leavin’ a procession of skinny-jeaned hipsters. Throughout, Blunt grins and giggles and belly-laughs, and if that can’t brighten your Monday, we’re not sure what else we could do. Enjoy!
