This week Justin Timberlake and Anna Kendrick, both stars of DreamWorks Animation’s upcoming feature Trolls, hit the 69th Cannes Film Festival to promote the film.

The duo also surprised a capacity audience in the Théâtre Claude Debussy at the Palais des Festivals with an acoustic rendition of Cyndi Lauper’s “True Colors,” which will be featured in the film’s soundtrack.

The performance followed a 20 minute preview of the film presented by DreamWorks CEO and co-founder Jeffrey Katzenberg, Trolls director Mike Mitchell, and co-director Walt Dohrn. Also in attendance were Trolls producer Gina Shay, DreamWorks Animation co-president of feature animation Mireille Soria, and 20th Century Fox CEO Jim Gianopulos.

Katzenberg commented on the film saying, “Our presentation today highlighted the animating strengths of Trolls: the unique and innovative world created by Mike, Walt and the creative team, the brilliant soundtrack produced by Justin Timberlake, and the incredible voice talents of Anna, Justin and the rest of the cast. While today was a huge success, we are even more confident that Trolls will delight audiences when it arrives in theaters.”

Following the presentation, Timberlake and Kendrick embarked on a speedboat and arrived in style at the Carlton pier, appearing alongside the models participating in a special Trolls themed fashion show on the pier. Guests of the DreamWorks-hosted Trolls tea at the adjacent Carlton Beach Restaurant were treated to the spectacle of the red carpet and fashion show, featuring models with brightly colored, gravity-defying hair created for they show by global long hair maestro Patrick Cameron and bespoke fashions by Patrick’s designer and collaborator Marco Erbi.

Soria told the audience, “Today’s activities provided only a small taste of the brightness, happiness and positivity of Trolls. Bonnie Arnold and I couldn’t be more thrilled that the collaborative efforts of DreamWorks’s unparalleled team of artists have received such a tremendous reaction in front of the Cannes audience.”

Added Shay, “Mike, Walt and I only wish we could have shared this experience with the entire Trolls creative team. We were truly heartened by the positive feedback, and look forward to sharing Trolls with the world later this year.”

The film will release in theaters this holiday season, telling the story of the overly optimistic Trolls. The creatures are song-lovers, and are oppressed by the comically pessimistic Bergens, who are only happy when they have trolls in their stomach.

The film will feature original music from Justin Timberlake, and soon-to-be classic songs from other popular artists, the film stars the voice talents of Anna Kendrick, Justin Timberlake, Christopher Mintz-Plasse, Russell Brand, Zooey Deschanel, Jeffrey Tambor, Christine Baranski, James Corden, Kunal Nayyar, Ron Funches, Icona Pop, Quvenzhané Wallis with John Cleese and Gwen Stefani.

Trolls will be DreamWorks Animation’s 33rd feature film release, joining a roster that includes many of the world’s most-beloved characters and franchises, including Shrek, Madagascar, Kung Fu Panda and How to Train Your Dragon. You can watch the official Trolls Trailer on YouTube.
