EXCLUSIVE: Star Trek’s Chris Pine co-wrote the comedy about a former child star.

Highland Film Group has added the reconfigured Chris Pine comedy Mantivities to its ambitious slate and is talking to buyers on the Croisette.

Pine wrote the screenplay and will produce the story with Sarah Babineau, Haven Entertainment’s Kevin Mann and Jordana Mollick.

Mantivities centres on a group of men who try to instil responsibility in their pal, a former child star, by taking him on a day of activities.

The film will also star real-life friends Robert Baker, Ian Gotler, Will Greenberg, Drew Howerton, and Tony Liebetrau – collectively known as The Button Factory.

16:14 Entertainment’s US-based business partner Sycamore Entertainment Group led by CEO Edward Sylvan will co-finance the project with Locmatel.

Val Hill and Ian McGloin of 16:14 Entertainment are the executive producers with Locomatel CEO Olivier Rossmann, Haven Entertainment’s Mauricio Betancur and Brendan Bragg.

“Rarely does a script depict such raw and hilarious male friendships while maintaining real truth and emotion at its core,” said Highland CEO Arianne Fraser and president of international sales Delphine Perrier. 

“Using their real life camaraderie, the Mantivities writers have created a universally appealing story that audiences will love and we couldn’t be more pleased to work with Chris and the rest of this fantastic team.”

Mantivities was previously set up at Waterstone.

Highland’s sales slate includes The Wright Girls with Jessica Alba and the Anchor Bay UK trio World War Dead, We Still Kill The Old Way and Age Of Kill.
