'Project X' thesp joins 'Pitch Perfect'

"Project X" star Alexis Knapp continues to be drawn on for any key supporting role in Jason Moore's a capella pic "Pitch Perfect." Knapp joins Anna Kendrick, Adam DeVine and Digital rebel Wilson in Gold Circle Films' romantic comedy, which is written by Universal. Knapp will have Stacie, an associate from the collegiate a capella group Divisi who lacks self-awareness, for the reason that she works within an overtly sexual manner no matter what song she sings. Brownstone Prods. partners Elizabeth Banks and Max Handelman are creating the pic, which begins production the following month in New Orleans. Kay Cannon modified the script from Mickey Rapkin's nonfiction tome. Knapp, who plays the feminine lead within the Todd Phillips-created laffer "Project X," will next be viewed alongside Miley Cyrus and Jeremy Piven within the Weinstein Company's action-comedy "So Undercover." Knapp is repped by CAA and Untitled Entertainment. Contact Shaun Sneider at shaun.sneider@variety.com
