Knapp joins Anna Kendrick, Adam DeVine and Rebel Wilson in Gold Circle Films’ romantic comedy, which will be distributed by Universal.
Knapp will play Stacie, a member of the collegiate a capella group Divisi who lacks self-awareness, in that she performs in an overtly sexual manner regardless of what song she sings.
Brownstone Prods. partners Elizabeth Banks and Max Handelman are producing the pic, which starts production next month in New Orleans. Kay Cannon adapted the script from Mickey Rapkin’s nonfiction tome.
Knapp, who plays the female lead in the Todd Phillips-produced laffer “Project X,” will next be seen alongside Miley Cyrus and Jeremy Piven in The Weinstein Company’s action-comedy “So Undercover.”
Knapp is repped by CAA and Untitled Entertainment.
