CAMERAS ROLL ON NEW LINE CINEMA’S “HOW TO BE SINGLE” Dakota Johnson, Rebel Wilson, Alison Brie, Damon Wayans, Jr. and Leslie Mann Star Under the Direction of Christian Ditter Principal photography is underway on New Line Cinema’s comedy “How to Be Single.” The film stars Dakota Johnson (“Fifty Shades of Grey”), Rebel Wilson (“Pitch Perfect”), Alison Brie (“Get Hard”), Damon Wayans, Jr. (“Let’s Be Cops”), and Leslie Mann (“This is 40,” upcoming “Vacation”), under the direction of Christian Ditter (“Love, Rosie,” “The Crocodiles”). There’s a right way to be single, a wrong way to be single, and then…there’s Alice. And Robin. Lucy. Meg. Tom. David. New York City is full of lonely hearts seeking the right match, be it a love connection, a hook-up, or something in the middle. And somewhere between the teasing texts and one-night stands, what these unmarrieds all have in common is the need to learn how to be single in a world filled with ever-evolving definitions of love.
